摘要: In this paper 2,4,6-triphenyl pyridine-functionalized polytyrosine (Pyridine-PTyr) was successfully synthesized by living ring-opening polymerization where 2,6-bis(4-aminophenyl)-4-phenylpyridine (Pyridine-NH2) the initiator. The photo-physical characteristics of Pyridine-NH2 and Pyridine-PTyr were elucidated via UV-vis absorption photoluminescence spectra, revealing that unlike Pyridine-PTyr, shows solvatochromic effects in solvents with different polarities. Additionally, exhibited aggregation-caused quenching (ACQ) phenomena; however, it became an aggregation-induced emission (AIE) material after attachment to rigid-rod conformation polytyrosine. Based on differential scanning calorimetry results, we observed blending P4VP a single glass transition temperature due their miscibility through intermolecular hydrogen bonding phenolic OH groups PTyr backbone pyridine ring revealed, as indicated IR spectroscopy. Obviously, intensity decreased hypsochromic shift from 536 489 nm, presumably release restricted intramolecular rotation triphenyl unit center polymer chains separated random coils based WAXD results.
