Abstract

Abstract:

A novel well-defined amphiphilic copolymer was prepared via atom transfer radical polymerization(ATRP) with 2-bromoisobutyrate-capped poly(9,9-dihexylfluorene) as macroinitiator and CuCl/HMTETA(1,1,4,7,10,10-hexamethyltriethylenetetramine) as the catalyst. The molecular weight and molecular distribution were well controlled, implying well-defined block structure of the prepared block copolymer. The chemical structure of the copolymer of PMaIpGa-PF-PMaIpGa was confirmed via ¹H NMR, FTIR and GPC. The copolymer could be successfully deprotected, and the final conjugated-carbohydrate block was found to be soluble in water. UV and PL spectra were also studied.

Key words: Conjugated block polymer, Carbohydrate-containing polymer, Polyfluorene, ATRP, Water-solubility
