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 PMalpGa-PF-PMalpGa was confirmed via H 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.
