论文摘要
许多基于有机材料的光电设备需要快速,远程单线激子传输。控制单线激子运输的关键因素包括材料的电子结构,疾病和激子 - 音波耦合。尚未探索对激子传输影响的重要参数是单元电子状态(S1)的对称性。在这里,我们采用飞秒的短暂吸收光谱和显微镜,以揭示S1的对称性与基于聚乙二醇的高度比分,近乎近期的一维共轭聚合物的对称性之间的关系。
Many optoelectronic devices based on organic materials require rapid and long-range singlet exciton transport. Key factors that control the transport of singlet excitons includes the electronic structure of the material, disorder and exciton-phonon coupling. An important parameter whose influence on exciton transport has not been explored is the symmetry of the singlet electronic state (S1). Here, we employ femtosecond transient absorption spectroscopy and microscopy to reveal the relationship between the symmetry of S1 and exciton transport in highly aligned, near-disorder free, one-dimensional conjugated polymers based on polydiacetylene.
