我们报告了两个弯曲的二烷氧基取代的萘二噻吩(bNDT)异构体以及相应的基于bNDT的小分子和聚合物半导体的合成和表征,用于有机场效应晶体管和有机光伏。与苯并二噻吩和线性萘二噻吩对应物相比,基于bNDT的构建基块具有更高的氧化电位以及光和空气稳定性。引入二烷氧基取代基可以从溶液中制备膜并控制分子固态堆积。在这些半导体中,聚合物P1表现出约0.4 cm 2 Vs -1的良好空穴场效应迁移率,且I on / I off > 10 4用于低温退火。这些结果表明,bNDT是光电子半导体材料的有前途的构建基块。

An electron-donating unit of the Formula, a copolymer thereof and their preparation methods, as well as their uses in thin-film transistor or polymer solar cell. The electron-donating unit is an effective building block for constructing high-performance polymer semiconductors due to its solubilizing ability, centrosymmetric geometry, backbone planarity, compact packing, and appropriate electron donating ability versus the previously reported BTOR and DTP units.

Disclosed are new semiconductor materials prepared from dithienylvinylene copolymers with aromatic or heteroaromatic π-conjugated systems. Such copolymers, with little or no post-deposition heat treatment, can exhibit high charge carrier mobility and/or good current modulation characteristics. In addition, the polymers of the present teachings can possess certain processing advantages such as improved solution-processability and low annealing temperature.
