A series of novel conjugated copolymers containing 9, 9-dihexylfluorene and europium complex-chelated benzoate units in the main chain had been synthesized through a three- step process, involving Suzuki coupling copolymerization, hydrolysis of benzoate units, and postchelation. The chemical structures of the copolymers were characterized by FT-IR, 1H NMR, 13C NMR, GPC, and ToF-SIMS. The copolymers exhibited relatively high glass ...
