Porphyrin with circularly polarized luminescence (CPL) in aggregated state was seldom presented due to the strong aggregation-caused quenching (ACQ) effect at aggregation. This work designed and synthesized a novel porphyrin derivative (CPL-P) with good CPL behaviour in aggregated states based on the strong AIE-FRET effect and good chirality transfer of liquid crystalline porphyrin, which was constructed by using porphyrin unit as core with four AIE cyanostilbene groups bearing peripheral chiral alkyl chains. CPL-P exhibited orderly hexagonal columnar mesophase between 62.5 °C and 113.2 °C. It displayed excellent fluorescence emission at 640–760 nm in aggregated states due to the AIE-FRET effect between cyanostilbene unit and porphyrin moiety. Moreover, CPL-P showed the strong circular dichroism and CPL properties in aggregated states based on the effective chiral transfer of the spiral liquid crystalline self-assembly. The |g_lum| value for mesophase attained 6.6 × 10⁻³ based on the combining effect of AIE-FRET and chiral transfer. This research supplied a new strategy for transferring typical achiral porphyrin with ACQ effect to luminescent molecule with good CPL behaviour in aggregated state.

由于聚集时强烈的聚集引起的猝灭（ACQ）效应，很少呈现聚集态的圆偏振发光（CPL）的卟啉。基于卟啉单元为核心，四个AIE为核心的液晶卟啉的强AIE-FRET效应和良好的手性转移，设计并合成了一种聚集态CPL行为良好的新型卟啉衍生物（CPL-P）。带有外围手性烷基链的氰基苯乙烯基。CPL-P在62.5°C和113.2°C之间表现出有序的六方柱状中间相。由于氰基茂金属单元和卟啉部分之间的AIE-FRET效应，它在640-760 nm的聚集状态下显示出出色的荧光发射。此外，CPL-P在螺旋液晶自组装体的有效手性转移的基础上，聚合体显示出强聚集态的强圆二色性和CPL性质。| g _lum | 基于AIE-FRET和手性转移的组合作用，中间相的值达到6.6×10 ^-3。这项研究提供了一种新的策略，将具有ACQ效应的典型非手性卟啉转移到聚集态具有良好CPL行为的发光分子上。
