$π$ -共轭聚合物薄膜的本征光学态
Essential optical states in $π$-conjugated polymer thin films
摘要：
我们开发了一个理论的电子结构和相互作用链的$π$共轭聚合物的物理理解的差异之间的解决方案和电影。光激发在溶液中只产生激子，而在薄膜中产生光激子和弱允许的激子。薄膜中的光致吸收主要来自最低的激基缔合物。我们也能够解释与光致发光，包括延迟光致发光和它的淬火电场相关的特点。
英文摘要：
We develop a theory of the electronic structure and photophysics of interacting chains of $π$-conjugated polymers to understand the differences between solutions and films. While photoexcitation generates only the exciton in solutions, the optical exciton as well as weakly allowed excimers are generated in films. Photoinduced absorption in films is primarily from the lowest excimer. We are also able to explain peculiarities associated with photoluminescence, including delayed photoluminescence and its quenching by electric field.
