Two donor–acceptor (D−A) copolymers, PEHBDT-BTz and PODBDT-BTz, containing the same backbone of benzodithiophene (BDT) and bithiazole (BTz) units but different sidechains were designed and synthesized. Effects of the sidechains of BDT and BTz units on solubility, absorption spectra, energy levels, film morphology, and photovoltaicproperties of the polymers were investigated. Results showed that

Mixed thiophene–N-methylpyrrole oligomers composed of the five and six heterocycles and hexyl substituents at both ends were synthesized, and their structural, electronic, and field-effect properties were investigated. These oligomers behaved as good p-type semiconductors on FET devices and the mixed hexamer with a nearly linear structure showed higher hole mobility (5.3 × 10−2 cm2 V−1 s−1) than that
合成了由两个末端的五个和六个杂环和己基取代基组成的混合噻吩-N-甲基吡咯低聚物,并研究了它们的结构,电子和场效应性质。这些低聚物在FET器件上表现为良好的p型半导体,具有接近线性结构的混合六聚物显示出比具有香蕉型五聚体的更高的空穴迁移率(5.3×10 -2 cm 2 V -1 s -1)。结构体。
