近日,香港中文大学(深圳)唐本忠团队报道了BODIPY蒽联萘化合物通过光激活AIE到ACQ转换显示老化驱动的窄带圆偏振发光增强。这一研究成果发表在2025年11月11日出版的《德国应用化学》杂志上。
圆偏振发光(CPL)材料因其在三维显示和信息加密等领域的应用前景而备受关注,目前研究主要聚焦于CPL活性的产生和不对称因子(glum)的提升。然而,高分辨率有机光电器件所需的窄带发射特性常被忽视。
研究组以蒽基团作为强组装单元、BODIPY作为窄带荧光团,并引入手性联萘基团构建材料。所得化合物R/S-An-BDP展现出光触发的聚集诱导发光(AIE)向聚集导致淬灭(ACQ)转变,并伴随CPL信号调控。此外,R/S-An-BDP在聚集态下呈现老化驱动的窄带荧光(半高宽FWHM为14 nm)和CPL活性(|glum|值为0.048),这归因于BODIPY与蒽单元的协同效应。该研究提出的功能基团融合策略为开发兼具高glum值和窄发射的CPL材料提供了新思路,有望推动高性能CPL材料的发展。

Abstract: The development of circularly polarized luminescence (CPL) materials has garnered considerable interest owing to their promising applications in areas such as 3D displays and information encryption, with most efforts devoted to generating CPL activity and improving the dissymmetry factor (glum). However, the essential requirement of narrow-band emission for high-resolution organic optoelectronic applications is often overlooked. Here we employed the anthracene group as strong assembly unit and BODIPY as narrow-band fluorophore to construct with chiral binaphthyl moiety. The resulting compounds R/S-An-BDP displayed light-triggered transformation from aggregation-induced emission (AIE) to aggregation-caused quenching (ACQ) with CPL signals regulation. Moreover, R/S-An-BDP showed aging-driven narrow-band fluorescence with the full width at half maximum (FWHM) of 14 nm and CPL activity with the |glum| value of 0.048 in the aggregate state, attributed to the combined effect of BODIPY and anthracene unit. These findings highlight a functional group fusion strategy for constructing CPL materials with large glum values and narrow emission, offering a promising approach towards high-performance CPL materials.
