Abstract The first synthesis of well‐defined poly(methylene‐ co ‐1,1‐diphenylpropenenylene) (C1‐ ‐C1’), equivalent to poly(ethylene‐ ‐diphenylbutadiene) copolymers was accomplished by C1 copolymerization novel diphenylpropenyl triphenyl arsonium ylides (Ph 2 AY) and dimethylsulfoxonium methylide (Me SY) using B‐thexylborepane as initiator. All polymerization conditions, including feed ratio, temperature, reaction time, were optimized. A series photoluminescent ‐diphenylbutadiene)s synthesized at different ratios, opening a new synthetic horizon for ‐disubstitutedbutadiene) copolymers. Notably, segment, arising from double bond rearrangement, confirmed NMR, resulting in an unprecedented two‐monomer three‐structure random terpolymer. An unexpected red‐shift phenomenon the fluorescence spectra observed with increasing ratio Ph AY copolymer. This shift is attributed aggregation diphenylbutadiene similar through‐space conjugation (TSC), likely induced decrease crystallinity Furthermore, another disubstituted allylic ylides, ( E )‐2‐phenylbutenyl ylide (MePhAY) also investigated. These additional compounds expand knowledge potential applications such techniques advanced materials.

Uniform sugar-functionalized polyesters combine the benefits of sugar's structural diversity, biocompatibility, and biodegradability with precise postfunctionalization capabilities, making them a highly valuable class materials extensive application potential. However, irregular placement hydroxyl groups has limited synthesis these polyesters. Here, we present first platform for uniform via regioselective ring-opening copolymerizations (ROCOPs) allopyranoside anhydrosugar epoxide (
