合成并彻底表征了由2-(3-硼基-2-噻吩基)噻唑衍生的三个受体-π-桥-受体(A-π-A)分子。在噻吩并噻唑中掺入BN单元并连接合适的受体部分可以得到具有较低LUMO水平的环境稳定的A-π-A分子。在真空沉积有机薄膜晶体管(OTFT)中测试了它们在有机电子领域的应用潜力。基于硼基-噻吩并噻唑和1,1-二氰基亚甲基-3-茚满酮(DCIND)受体部分的OTFT器件的电子迁移率约为1.4×10 -2 cm 2 V -1 s -1在空气中,这是迄今为止有机硼小分子报道的最高电子迁移率。相反,采用丙二腈(MAL)衍生物作为活性层的器件没有显示任何电荷传输行为。正如茚满二酮(IND)和MAL衍生物的单晶X射线分析所表明的,与MAL分子相比,IND(和DCIND)迁移率的提高可归因于所赋予的固态中有效的二维π堆积由具有扩展π表面的受体部分组成。

parameters of conjugated polymers are lowest unoccupied molecular orbital (LUMO) and highest occupied molecular orbital (HOMO) energylevels. Few approaches can simultaneously lower LUMO and HOMOenergylevels of conjugated polymers to a large extent (>0.5 eV). Disclosed herein is a novel strategy to decrease both LUMO and HOMOenergylevels of conjugated polymers by about 0.6 eV through replacement of a CC

D–π–A Dyes with an Intramolecular B–N Coordination Bond as a Key Scaffold for Electronic Structural Tuning and Their Application in Dye-Sensitized Solar Cells
A series of D–π–A dyes (AK1–5) was designed and synthesized for applications in dye-sensitizedsolarcells (DSSCs). AK1–5 contain triphenylamines as electron donors (D), bithiophene π-spacers, boryl-substituted thienylthiazole as electron acceptors (A), and carboxylic acid derivatives as anchor groups. Electrochemical and photophysical measurements on AK1–5 revealed that the use of boryl-substituted

The synthesis of a series of conjugated organophosphorus materials with intramolecular Lewisacid/base interactions and the exploration of the electronic nature of the bonding around the resulting hypervalent phosphorus centers are reported. To further establish the influence of increasing the size of the π-conjugated backbone, two scaffolds, thiazolyl-thiophene and benzothiazolyl-thiophene, were included

Provided is an inexpensive and high-performance dye compound that does not use an expensive precious metal and does not require the use of a strong electron-withdrawing group. The compound is formed such that a boron substituent is introduced into a heteroatom-containing π electron-based backbone containing a double bond between carbon and the heteroatom to obtain a compound in which a backbone having boron and a coordination bond in a molecule thereof is used as a π electron-accepting backbone.
