摘要

在共混的两种共轭聚合物中

采用分子自组装技术制备了嵌段共轭聚合物量子线的异质结构

通过室温下吸收光谱、发光光谱和激发光谱的研究证实了在这种嵌段共轭聚合物量子线的异质结构中存在很强的激子限制效应以及链内和链间的有效能量传递。

Abstract

An ABA triblock conjugated polymer with strong two dimensional quantum confinement of excitons was synthesized by self-assembly of two block conjugated polymers in binary blends

the heterostructures were prepared. The spatial confinement of excitons

and microphase separation as well as efficient energy transfer via interchain and intrachain mechanisms in the ABA triblock polymer heterostructures were shown by optical absorption

photoluminescence

and photoluminescence excitation spectra of the triblock polymer at room temperature.
