摘　　要：Two types of polysiloxanes, which contain both C 60 moieties and carbazolyl groups in the side chains with a difference in the numbers of the reacting site on C 60 molecules, were synthesized and their fluorescent properties were studied to distinguish the role of C 60 in the luminescent polymers. Our results demonstrated that when C 60 moieties are bonded to the polymers as multisubstituents but not linked to the luminescent moieties directly, the luminescence of the resultant polymers were still very strong instead of quenching, even the substituted degree is only 1 01.Two types of polysiloxanes, which contain both C 60 moieties and carbazolyl groups in the side chains with a difference in the numbers of the reacting site on C 60 molecules, were synthesized and their fluorescent properties were studied to distinguish the role of C 60 in the luminescent polymers.
