In the paper we present synthesis and characterization of new donor–acceptor thiophene derivatives (TDs) containing vinylbenzo[d]thiazole, vinylpyridine and 1H-imidazo[4,5-f][1,10]phenanthroline residues. Using CELIV method, electron and hole mobility have been studied in the polymer layers based on poly [9,9-bis(6-diethoxyl-phosphorylhexyl)fluorine] (PF-EP) doped with the TDs. Polymer light-emitting diodes (PLEDs) containing newly synthesized polyfluorene (PF) as emitting layers and PF-EP/TD composites as electron transporting layers show higher brightness at 15V as compared with TD free PF-EP.

通过与噻吩衍生物形成复合物来改变导电PF-EP聚合物的载流子迁移率

在本文中，我们介绍了含有乙烯基苯并[d]噻唑，乙烯基吡啶和1H-咪唑并[4,5- f ] [1,10]菲咯啉残基的新型供体-受体噻吩衍生物（TDs）的合成和表征。使用CELIV方法，已经研究了掺杂TDs的基于聚[9,9-双（6-二乙氧基-磷酰基己基）氟]（PF-EP）的聚合物层中的电子和空穴迁移率。与不含TD的PF-EP相比，包含新合成的聚芴（PF）作为发射层和PF-EP / TD复合材料作为电子传输层的聚合物发光二极管（PLED）在15V时显示出更高的亮度。
