近几年来,人们对有机材料尤其是带有π共轭双键的导电聚合物产生了极大兴趣,因为这类导电聚合物在结构上具有和无机半导体(如Si等)材料的相似性,而且还可根据一定的设计要求,通过改变它们的聚合度来获得所需要的能带宽度.另外,可通过极为方便的甩胶涂膜(RC)或浸没涂膜(DC)等方法对这些聚合物进行制膜.目前,人们已经用聚合物材料制成了具有不同功能的有机薄膜晶体管,如Schottky门电路和绝缘门电路薄膜晶体管.在这些聚合物中,特别引人注目的是聚烷基噻吩.它不仅是一种可溶性的导电聚合物,而且还具有独特的物理化学特性,如热致变色、溶致变色现
In recent years, great interest has been made in organic materials, especially conductive polymers with π-conjugated double bonds, because such conductive polymers have structural similarities with materials of inorganic semiconductors such as Si, But also according to certain design requirements, by changing their degree of polymerization to obtain the required bandwidth.Moreover, these methods can be easily polymerized by such methods as RC coating or immersion coating (DC) Materials for film formation At present, organic thin film transistors having different functions, such as Schottky gates and insulated gate thin film transistors, have been made from polymer materials, Among these polymers, particularly attractive are polyalkyl It is not only a soluble conductive polymer, but also has unique physicochemical properties such as thermochromism,
