导电聚合物是20世纪70年代发展起来的一个新兴研究领域,因其在有机光电子学中诱人的应用前景备受关注.但是,目前大部分的聚合物光电器件都是基于薄膜构筑的,大量的缺陷及无规的分子排列不利于我们对材料本征性能的评估及高性能光电器件的构筑.有机单晶具有分子长程有序、低缺陷和无晶界等优点,是用来解决这些问题的最佳选择,但是高质量聚合物单晶的获得一直都是一个挑战性的问题.本文综述了目前有关共轭聚合物微纳晶的制备、表征及其在场效应晶体管器件应用中的研究进展,并对共轭聚合物微纳晶材料与器件的发展前景和面临的一些问题做了简要的讨论.
Conductive polymers are an emerging field of research developed in the 1970s and are attracting much attention because of their attractive applications in organic optoelectronics.However, most of the current polymer photoelectric devices are based on thin films, and a large number of Of defects and random molecular arrangement is not conducive to our evaluation of the intrinsic properties of materials and the construction of high performance optoelectronic devices.Organic single crystal has the advantages of molecular long range order, low defect and no grain boundary, is used to solve these problems , But the acquisition of high quality polymer single crystal has always been a challenging issue.In this paper, the recent progress in the preparation, characterization and application of the field-effect transistor , And briefly discussed the development prospects and some problems faced by conjugated polymer micro-nano materials and devices.
