Abstract

BN-embedded anthracenes with chiral 3,7-dimethyloctyl side chains (namely (S,S)- and (R,R)-DPBNA) have been synthesized as novel visible-blind ultraviolet-absorbing chiral materials for ultraviolet circularly polarized light (CPL) detection. Phototransistors with a p–n heterojunction configuration have been fabricated with (S,S)/(R,R)-DPBNA serving as the p-type photoactive layer and an achiral n-type polymer as the electron transport layer. Significant discrimination between left and right CPL has been observed under 365 nm CPL irradiation with an average photocurrent dissymmetry factor of 0.033, highlighting the potential of BN-embedded semiconductors for ultraviolet CPL detection.

基于手性 BN-蒽衍生物的紫外圆偏振光探测技术†。

我们合成了具有手性 3,7 二甲基辛基侧链的 BN 嵌入蒽（即 (S,S)- 和 (R,R)-DPBNA) 作为用于紫外圆偏振光 (CPL) 检测的新型可见光盲紫外吸收手性材料。以(S,S)/(R,R)-DPBNA 作为 p 型光活性层，以非手性 n 型聚合物作为电子传输层，制造出了具有 p-n 异质结结构的光晶体管。在 365 nm CPL 辐照下，观察到左侧和右侧 CPL 有明显的区别，平均光电流不对称系数为 0.033，这凸显了嵌入 BN 的半导体在紫外 CPL 检测方面的潜力。
