Unexpected Strong Luminescence of Polysiloxanes Containing Carbazolyl and C₆₀ Moeities as Side Chains

Abstract

Two typea of polysiloxanes , which contain both C, moieties and carbazolyl groups in the side chains with a difference in the numbers of the reacting site on C, molecules, were synthesized and their fluorescent properties were studied to distinguish the role of Ca in the luminescent polymers. Our results demonstrated that when Ca 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.
