an electron mobility of 1.02×10−4 cm2 V−1 s−1 and a relatively balanced holemobility of 8.76×10−5 cm2 V−1 s−1. In contrast, PCzSi‐alt‐PDBTSi exhibits an electron mobility of 4.65×10−5 cm2 V−1 s−1 and a holemobility of 1.17×10−4 cm2 V−1 s−1. Therefore, our results here provide a feasible strategy to obtain solution‐processed polysiloxane materials with high and balanced electron‐ and hole‐transporting
我们设计并合成了一个基于二氧化二苯并噻吩homopolysiloxane,PDBTSi,和咔唑-二苯并噻吩二氧化物交替copolysiloxane,PCzSi- ALT -PDBTSi,分别。既PDBTSi和PCzSi- ALT -PDBTSi具有改善的溶解性,良好的成膜能力和非常高的热稳定性,因为引入聚硅氧烷主链。同时,PDBTSi和PCzSi- ALT -PDBTSi表现分别2.95 eV和3.05 eV的,高三重态能量水平。此外,PDBTSi具有良好的电子传输性能,电子迁移率为1.02×10 -4 cm 2 V -1 s -1和相对平衡的空穴迁移率为8.76×10 -5 cm 2 V -1 s -1。与此相反,PCzSi- ALT -PDBTSi表现出4.65×10的电子迁移率-5 厘米2 V -1 小号-1和1.17×10的空穴迁移率-4 厘米2 V -1 小号-1。
