Abstract
A well-defined fluorescent star-shaped polymer containing two different fluorescent functionalities one in the main chain and another in the end group was designed and synthesized by combining atom transfer radical polymerization (ATRP) and azide-alkyne click reaction. The star polymer with four arms was prepared from copolymerization of methyl methacrylate and 4-(2-(9-anthryl))-vinyl-styrene using ATRP. Subsequently the end group was modified with another fluorescent moiety by click coupling. The structure of all the intermediate and final products was established through NMR spectroscopy, Fourier transform infrared spectroscopy, gel permeation chromatography, UV−visible spectroscopy and fluorescence spectroscopy. The novel hybrid polymer exhibits an attractive high fluorescence at 494 nm and over a broad range which was a combination of both the fluorescence moieties. © 2013 Society of Chemical Industry
