I Have a Research Support System

Text 396 It is not a problem to send a hundred articles (for subscription)

Xu Qiu restricts the autonomous research direction in the simulation laboratory iii to the effective layer structure of polymer donor/small molecule receptor, which is generally three optimization directions.

The first is the donor material. On the one hand, it can be further optimized based on the existing molecules such as h43 and j2. In this regard, the school girls have done very well before. Although the optimization space is not large, there is still a squeeze. For example, optimization of side chain length or type, introduction of other heteroatoms, replacement of thiophene side chain structure, etc.

On the other hand, other structures can also be used. This structure does not have to be a brand-new structure. It is entirely possible to find a unit from the classic donor material molecules of pce10, pce11 or even p3ht, and improve the splicing to make the donor material The forbidden band width is about 1.7-2.0, which can obtain medium band gap or wide band gap materials to match with narrow band gap non-fullerene acceptors such as itic.

For specific operations, a benzene ring can be introduced into the main chain of pce11 to form a pbt4t-b structure. The introduction of the benzene ring destroys the overall regularity of the molecule, reduces the crystallinity of the molecule, and also allows the forbidden band width of the molecule. improve.

Or modified based on p3ht to design a polythiophene structure with a relatively low cost and a relatively simple molecular structure. This is also a feasible idea. Perhaps the cost of the device can be reduced through this approach. However, p3ht itself is not compatible with itic , Xu Qiu tried very early and the efficiency was only less than 2%, which is a thrashing system.

Second is the receptor material. There are more articles that can be done here.

First, focus on the a unit, which is based on the current i unit to modify.

It can be changed slightly, namely introducing some other groups on the terminal benzene ring.

In this regard, Xu Qiu and the others have done more research before, introducing chlorine, fluorine, methyl and so on. The postdoctoral sister also published a "six in one" work, which is specifically for this.

Of course, there is still room for research, such as taking out the synthetic ideas based on itic polymer acceptor materials that were temporarily put down, that is, introducing a bromine group on i to synthesize itic-br, and make it compatible with bistrimethyltin The substituted thiophene unit undergoes a stille coupling reaction to obtain a p-itic-t polymer acceptor material.

It can also be greatly changed, i is a five-membered ring and a six-membered benzene ring connected by a fused ring to form an indenedione structure. This five-membered and six-membered fused ring structure can be modified.

For example, changing a six-membered benzene ring to a five-membered thiophene ring is a condensed ring structure of two thiophene rings. According to the orientation of the thiophene ring, there can be two different connection methods.

For another example, changing the benzene ring to a naphthalene ring, that is, two parallel benzene rings, increases the conjugation length of the i unit.

Second, focusing on the central d unit, there will be more room for improvement.

The lateral conjugation length can be modified, different main chain structures can be designed, the side chain positions can be modified, and heteroatoms can be introduced.

If the brain hole is released, various molecular structures can be designed, such as l-type, x-type, m-type, y-type...

It is even possible to deliberately destroy the conjugate structure.

The conjugate structure in organic photovoltaic materials is a double-edged sword.

On the one hand, it is easier to realize ππ stacking between molecules, which is beneficial to the transport of excitons and obtains high photoelectric conversion efficiency;

On the other hand, there are double bonds in the conjugated structure, which is unstable under illumination, especially ultraviolet light, and it is easy to open the double bonds, destroying the conjugated structure itself, resulting in poor stability of the material.

If a non-conjugated acceptor material can be developed, its device stability is definitely very strong.

Third, you can also change the connection structure of the unit. Itic is the ada structure, and the idtbr of the school sister and Xu Zhenghong is aπdπa.

Originally, both ada and aπdπa are symmetrical structures. A series of variant structures can be designed, such as adda, addda, adada, and even more complex adada structures......

If you want to, asymmetric structures like daa and dda can be designed, but the synthesis will be more difficult, and maybe no one wants to do it.

Finally, if you focus on the device, it is a series of means such as translucency, large size, flexibility, scratch coating, lamination, non-halogen solvents...

If you count them down, there are still quite a few articles that can be published. There are 20 to 30 articles, large and small, if you don’t talk about them, and if you have more, you can publish a hundred articles.

Of course, with so much work, Xu Qiu's small team of five and a half people certainly can't eat them all. Even if Xu Qiu gets all the experimental results, it takes a lot of time to repeat and write articles in reality.

I can only focus on the big and let go of the small, and then it will be up to the team of other research groups to see how many articles can be snatched from Xu Qiu.

On the morning of October 2nd, Xu Qiu and Han Jiaying showed up at the Magic City Airport and were going to Yucheng. They had booked the hotel and air tickets in advance.

The two planned a five-day tour of Yucheng during the National Day early.

On the one hand, it is the combination of work and rest, which exceeds the work intensity of 996 for a long time and needs to relax appropriately.

On the other hand, the sum of the bonuses they received for posting articles is already tens of thousands, which is a huge sum of money for the students. The money earned is always spent.

Moreover, aren’t they all talking about economic internal circulation, which can be regarded as stimulating domestic demand and making a concrete contribution to the country.

In five days, the two of them ate all the major delicacies in Yucheng, such as Diaobao Huaeryu, Yucheng old hot pot, Yangjilong’s special Yucheng cuisine, fatty chicken, Yucheng noodles...

The taste of the dishes is mostly not bad, the characteristic is that it is more oily and spicy, and the price is much cheaper than that of Magic City and Sioux City.

The only problem is that after eating for five days, the stomachs of the two are a little uncomfortable, and the chrysanthemums are also a bit hot.

During the holidays, Xu Qiu also brought a computer to prevent any accidents, but it was not used and did not receive Wei Xingsi's phone harassment.

Happy time is always short, and in a blink of an eye, the five-day holiday passed.

On October 7th, Thursday afternoon, everyone gathered again for a 216.

Xu Qiu and Han Jiaying brought some Dengying beef back to the other friends, which is regarded as a specialty of Yucheng.

There are not many special products in Yucheng that can be given away. Specialties such as Jiangjin Rice Flower Candies and Ciqikou Chen Mahua may be good for people of the previous generation, but young people rarely eat them now.

In the end, the two chose between Dengying Beef and Hot Pot Ingredients. After choosing the former, they couldn't deliver hot pot ingredients.

Others also shared their holiday experiences.

Tian Qing ran out again. This time she went to Mongolia. She brought some cheese and beef jerky to everyone, and said cheerfully: "Riding a horse bala bala...a yurt and a whole sheep feast bala bala... Grassland Barabala... I didn't encounter the wolf Barabala... It turns out that the tap water in the grassland is also running water. I always thought it was milk..."

After chatting for a while, Wei Xingsi appeared at the door of 216 and waved to Xu Qiu: "Xu Qiu, come to my office."

The two entered 218. Wei Xingsi pours the farmer's three punches into the drinking fountain and starts to boil the water, while casually asking: "Have you been out for fun during the holidays?"

"Yes, I went to Yucheng with Han Jiaying. By the way, I also brought some Dengying beef. I will bring you a pack later." Xu Qiu responded.

"No, you can keep it for yourself." Wei Xingsi waved his hand, returned to the desk, and said with joy: "I called you over. There are several things. First of all, we received the "Joule" journal. For a draft, let’s write a review of itic non-fullerene receptor materials."

After a pause, Wei Xingsi said: "I originally planned to vote for a "Nature" journal er., which specializes in review articles, after a while. Now that "Joule" has issued a draft, I will vote for "Joule." Okay, the manuscript article is basically stable. This article does not need to bring too many people, just the two of us. You can lead the writer, how about it?""

"No problem." Xu Qiu nodded in response. This is a summary of the recent work of the team and other followers. It is still very beneficial. It can grasp the future research direction more clearly. Moreover, this is equivalent to nothing. There is no reason to reject an article at the level of a major journal of Nature.

Wei Xingsi gave an "um" and continued: "In addition, search for your itic am article on the wos website. It should be updated now. Check if there are any signs of highly cited and hot articles. I guess At least one is highly cited, if you have one, remember to take a screenshot."

Next, Wei Xingsi took a thick stack of documents from the desk next to him and handed it to Xu Qiu: "There are also some recent documents. I have browsed it roughly, and other research groups have begun further research based on itic. Some of them It’s very similar to our job~www.ltnovel.com~ Please be careful not to collide with other people."

"Okay." Xu Qiu picked up the document and was about to leave. Wei Xingsi said again: "Finally, inform them that the group meeting will not be held today and will be held next Monday."

Xu Qiu returned to 216, and Han Jiaying leaned over and asked curiously: "Brother, what is Miss Wei looking for?"

"There will be no group meeting in the afternoon, and we will write an itic review of "Joule"..." Xu Qiu shared some major news with other people in the group.

Then Xu Qiu turned on the computer, logged into the wos website, and retrieved his itic article published on am.

Sure enough, this article has already appeared as a highly cited and hot article.

"Brother, this is your second Grand Slam article." Han Jiaying stared at Xu Qiu's computer screen and said: "The number of real-time citations...wow, it has reached 38 times. When Brother checked it last month, it seemed It’s less than 20 times. This month, the number of citations for articles has doubled."

"Basic operation." Xu Qiu casually responded, saving the screenshots of the symbolic high cited and hot articles Little Crown and Flame, and searched for the previous pce11 work, which is his first Grand Slam article. .

Now the number of real-time citations has reached 61 times, and it is also a highly cited article and a hot article.

Xu Qiu originally thought that the hot spot logo would drop. After all, flowers bloom and dynasties change, everything is the same, and an article cannot always be a hot spot.

As a result, he didn't drop, so he posted two articles at the same time.

Moreover, the work in different sub-fields is really rare.
