摘要： 合成一种新的金属铬有机单体N-乙烯基咔唑三羰基铬,经元素分析、IR和1HNMR确证和表征.研究结果表明,N-乙烯基咔唑三羰基铬能发生自由基聚合反应,得到结构单元含等物质的量铬的金属有机高分子,苯环及含氮给电子中心的共轭效应能在一定程度上弥补由Cr(CO)3基团吸电子诱导效应引起的单体聚合活性的下降

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
