The one-pot terpolymerization of epoxide (EP), anhydride (AH), and CO2 to synthesize polyester-polycarbonate copolymers with precise sequences remains a significant challenge in polymer chemistry. In this study, promising progress was achieved by utilizing cyclic trimeric phosphazene base (CTPB) triethylboron (TEB) as binary catalyst, enabling the synthesis both well-defined block truly random poly(ester-carbonate) through EP/AH/CO2. By adjusting molar ratio CTPB/TEB 1/0.5, remarkable chemoselectivity for ring-opening alternating copolymerization (ROAC) propylene oxide (PO) phthalic (PA) achieved, followed ROAC PO/CO2. This sequential control allowed copolymers, containing three possible sequences, ester-ester sequence (EE)/ester-carbonate (EC)/carbonate-carbonate (CC) = 59/4/37, from mixture PO, PA, CO2. Moreover, versatility catalyst regulating demonstrated, 1/3 facilitating simultaneous PO/PA PO/CO2 compatible rates, resulting production which (EE/EC/CC 26/50/24) are very close theoretical values. metal-free catalytic system its flexible regulation strategy proved be applicable wide range epoxides (PO, cyclohexene (CHO)) anhydrides (PA, diglycolic (DGA), succinic (SA)), successful diverse compositions.

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.
