本文研究了聚(9,9-二辛基芴)(PFO)和给体-受体型共聚物聚(9,9-二辛基芴-alt-苯并噻二唑)(F8 BT)的物理和化学结构对它们手性光学响应的影响。我们揭示了电磁耦合的意义,在短(分子水平)和中间(离域超过多个聚合物链)的长度尺度上,不对称的大小。这些发现提供了一个框架,设计新材料与增强的手握光学响应。
We study the influence of the physical and chemical structure on the chiroptical response of fluorene-based polymeric systems, namely poly(9,9-dioctylfluorene) (PFO) and the donor-acceptor type copolymer poly(9,9-dioctylfluorene-alt-benzothiadiazole) (F8BT). We reveal the significance of electric-magnetic coupling, at both short (molecular-level) and intermediate (delocalised over multiple polymer chains) length scales, on the magnitude of the dissymmetry. These findings provide a framework for the design of new materials with an enhanced chiroptical response.
