螺烯型化合物因具有独特的手性特性而备受关注, 但获得其单一对映体通常需要耗时且昂贵的手性拆分. 此外, 这类化合物的手性光学响应通常局限于紫外光区. 针对这些问题, 提出了一种简便的策略: 通过在β-异靛蓝骨架氮杂-氟硼二吡咯(BODIPY)类似物(BIABs)母核结构的外围引入光学纯的联萘酚基团, 制备了6个具有光学活性的化合物. 所得的(R)/(S)-联萘酚-BIABs不仅表现出优异的光稳定性, 还展现出深红光发射、显著的科顿效应(Δε)以及高吸收不对称因子(gabs)等特点. 同时, 这些化合物在深红区域实现了可调控的圆偏振发光(CPL), 并具有较高的CPL发光亮度. 该策略为光学活性化合物的合成提供了一种通用性强、操作简便的新途径.

Helicene-type compounds are renowned for their unique chiral properties, however, obtaining their enantiomers usually requires laborious and costly chiral separations. Moreover, their chiroptical activity is typically limited to the ultraviolet spectral range, which restricts their broader applicability. To overcome these limitations, a novel and efficient strategy for synthesizing optically active compounds through the incorporation of an optically pure binaphthol (BINOL) group onto the periphery of β-isoindigo based aza dipyrrometheneboron difluoride (aza-BODIPY) analogues (BIABs) was presented. The resulting (R)/(S)-BINOL-BIABs demonstrate exceptional photostability, deep-red emission, strong Cotton effect (Δε) and high absorbance dissymmetry factor (gabs). Moreover, tunable circularly polarized luminescence (CPL) with high brightness in the deep-red region was achieved. This strategy offers straightforward procedures for synthesizing optically active compounds.
