摘要

在功能染料中

由于苝四酰二亚胺独特的光学及光物理性质

引起了人们广泛重视

但是制备一维苝四酰二亚胺结构尚是一种挑战.合成了二(正丁基)苝四酰二亚胺衍生物

通过对溶剂的选择

用自组装方法得到了其一维微纤结构

FESEM及TEM表明该微纤结构有1～2个微米宽

几百个微米长.XRD结果表明其内部结构高度有序.对其机理研究表明

苝四酰二亚胺核之间的π-π堆积和憎溶剂效应以及正丁基较小的空间位阻对微纤的形成起重要作用

由于微纤中苝四酰二亚胺分子的紧密堆积

引起苝四酰二亚胺核强烈的π-π相互作用使得苝四酰二亚胺激发态分子间电荷迁移作用增强

不论是其UV-Vis吸收光谱还是其发光光谱都有较大红移

其光学性能同相应的溶液比较有很大差别.苝四酰二亚胺在维度可控光电器件的应用方面提供了有益的实验数据

使其在光捕集系统、光电电池、场效应晶体管以及发光二级管的应用研究方面可能成为有前途的材料之一.

Abstract

Among functional dyes

perylene diimides have been of great interest due to their unique optical and photophysical properties.But the manipulation of superlong

Dstructure of perylene diimides

however

is still a challenge.In this paper

superlong microfiber of bis(n-butyl) substituted perylene diimide(1) has been obtained by solvent evaporation method.FESEM and TEM micrographs indicate that the microfibers are 1~2 μm wide and several hundred micrometers long.XRD measurement demonstrates that the walls of the microfiber are arranged in highly ordered nanoscopic structure.Driving force for the formation of microfiber has been proposed

i.e.

cooperation of solvophobic effect for molecules(1) and π-π stacking interaction between the perylene diimide cores.The effect of the closely packed structure on its photophysical behavior is demonstrated by the UV-Vis absorption and fluorescence spectra.
