Abstract

Abstract: Anovel metal chromium containing organic monomer, N-vinylcarbazole chromium tricarbonyl has been synthesized and the structure has been confirmed by elemental analysis, IRand ¹H NMRspectra. N-vinylcarbazole chromium tricarbonyl can undergo free radical polymerization reaction to provide an organometallic polymer which contains equivalent chromium in its structural unit. It was observed that the decrease of polymerizing activity of the monomer caused by the electron withdrawing effect of Cr(CO)₃ could be compensated to some extent by the conjugational effect between the benzene ring and nitrogen containing electron donor centers.

Key words: N-Vinylcarbazole, Chromium tricarbonyl, Synthesis, Polymerization
