Abstract
Abstract Polystyrene incorporating carboxylate group as α‐end was synthesized by using initiator 4‐chloromethyl benzoic acid via atom transfer radical polymerization. Its ω‐chlorine end‐group was transformed by cumic acid, diethyl malonate, and thiol, respectively, to form end‐functionalized telechelic polystyrenes. These PSts with different functionalized ω‐end group (PSt 1 , PSt 2 , and PSt 3) were obtained and characterized by H NMR and TGA. This type of end‐functionalized telechelic polymers can further act as polymeric ligands to form polymeric metal complexes. In this study, PSt 1 with carboxylate group at each end was allowed to react with Eu(DBM) 2 Cl·2H 2 O to afford a new polymeric complex PSt 1 ‐Eu(III) showing significant red‐light emission. Moreover, the film of PSt 1 ‐Eu shows similar emission pattern with its DMF solution. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
