Preparation, Characterization and Photoconductivity of C60 Grafted Poly(N-vinyl carbazole)

Abstract

Abstract: The C₆₀ grafted poly(N-vinyl carbazole) (PVK) polymer(CGP) was prepared by simple radical polymerization initiated by BPOat 90℃.The products were characterized by UV-Vis, FTIR, GPCand fluorescence and it was proven that C₆₀ was grafted covalently to the PVK. The C₆₀ moiety in the product was about 1. 2% (mass fraction). The photoconductlvity study revealed that the photoconductivity of PVKwas improved obviously through grafting C_60.The half time of light decaying (t1/2) of CGPreached 0. 35 s.

Key words: Poly(N-vinyl carbazole) (PVK), C₆₀, C₆₀ grafted PVK, Photoconductivity
