• 关键词: molecular orientation; semiconducting polymer

In this year, the objective is to control the orientation of semiconducting polymers in thin films, and understand its influence on the relevant thin film physical properties and the performance of organic electronic devices. Two strategies, namely (1) the use of surface-segregated monolayer and (2) the modification of side groups by phytol-derived alkyl chains were utilized. In the first subtopic, simultaneous control of molecular orientation and chirality in thin films was fulfilled by self-assembly of fluoroalkyl modified chiral polythiophene.In the second subtopic, phytol derivative was utilized as a new class of alkyl chain for semiconducting polymers to realize the balance between solubility and film crystallinity with controlled chain orientation, thus improved device performance.Two academic papers of the aforementioned studies are now in preparation.

在今年，目的是控制薄膜中半导体聚合物的方向，并了解其对相关薄膜物理特性和有机电子设备的性能的影响。两种策略，即（1）使用表面分离的单层和（2）使用植物衍生的烷基链对侧基进行修饰。在第一个亚主题中，通过氟烷基修饰的手性聚噻吩的自组装来实现薄膜中分子方向和手性的同时控制。在溶解度和膜结晶度之间具有受控链方向，从而提高了设备​​性能。上述研究的两项学术论文正在准备。
