Synthesis and Characterisation of Biodegradable Copolymer Containing Phthalocyanine by Ring-Opening Polymerization

Abstract

In this study, well-known biodegradable poly [(β-butyrolactone-block-ethylene glycol methyl ether)-phthalocyanine- (β-butyrolactone-block-ethylene glycol methyl ether)] abbreviated as poly(BL-b-mEG)-Pc-poly(BL-b-mEG) copolymer was synthesised. In the first part, poly (β-butyrolactone-block-ethylene glycol methyl ether) [poly(BL-b-mEG)] block copolymer was prepared by ring-opening polymerisation (ROP) method of β-butyrolactone using poly (ethylene glycol) methyl ether. In the second part, poly(BL-b-mEG)-Pc-poly(BL-b-mEG) copolymer was obtained from the reaction poly(BL-b-mEG) block copolymer, SiPcCl2, and K2CO3. Axial binding of poly(BL-b-mEG) block copolymers to the phthalocyanine compound was achieved. The synthesised products were characterised by using multi-instruments such as1H-NMR, FT-IR, GPC, ve UV-visible. The electronic and singlet oxygen production capacity of poly(BL-b-mEG)-Pc-poly(BL-b-mEG) copolymer was investigated. © 2024 Informa UK Limited, trading as Taylor & Francis Group.
