Comprehensive Summary As a class of organic dyes, boron‐containing compounds play an important role in luminescent materials. They have attracted considerable attention due to their unique photophysical properties. Chiral systems wide range practical applications biological imaging, optoelectronic devices, information storage and 3D display. Boron‐containing chiral materials can not only effectively improve the properties CPL materials, but also bring system, which enables them be used as favorable emitting for expanded applications. Here, we review research progress by detailed discuss according different skeletons, such point chirality, 1,1’‐binaphthyl, [ n ]helicenes, [2,2]paracyclophane pillar[5]arenes. We believe that this is significance development Key Scientists The studies circularly polarized luminescence (CPL) based on small molecules advanced significantly. However, gained recent years. In 2019, Zhao's group prepared binaphthalene derivative modified with triarylborane, representing molecule material exhibit characteristics responsive both solvent fluoride ions. 2020, Chen's steric effects triarylborane triphenylamine prepare planar 2021, Wang's developed new B,N‐embedded double hetero[7]helicenes strong chiroptical responses UV‐visible region. same year, He's asymmetric reactions synthesize boron‐based point‐chirality high efficiency enantioselectivity. 2023, Ravat synthesized 1,4‐B,N‐embedded helicenes exhibiting narrow‐band fluorescence CPL. During period, Matthias Wagner et al obtained (BO) 2 ‐doped tetrathia[7]helicene via efficient four‐step synthesis, Zheng reported nearly pure green electroluminescent device (CP‐OLED). 2024, hetero‐[9]helicenes offering pathway towards significantly enhanced helicene‐based CPEL.

Abstract Boron compound BOMes 2 containing an internal B−O bond undergoes highly efficient photoisomerization, followed by sequential structural transformations, resulting in a rare eight‐membered B, O‐heterocycle (S. Wang, et al. Org. Lett . 2019 , 21 5285–5289). In this work, the detailed reaction mechanisms of such unique carbonyl‐supported tetracoordinate boron system first excited singlet (S 1 ) state and ground 0 were investigated using complete active space self‐consistent field its second‐order perturbation (MS‐CASPT2//CASSCF) method combined with time‐dependent density functional theory (TD‐DFT). Moreover, imine‐substituted tetracoordinated organic (BNMes was selected for comparative study to explore intrinsic reasons difference reactivity between two types compounds. Steric factor found influence photoisomerization activity BNMes These results rationalize experimental observations can provide helpful insights into understanding excited‐state dynamics heteroatom‐doped organoboron compounds, which facilitates rational design boron‐based materials superior photoresponsive performances.
