N-乙烯咔唑(N-VCz)是较强的电子给体,很易进行电荷转移聚合。因此近几年对它的研究颇多。但用同类化合物作为引发剂作系统研究却报道极少。我们制备了2-硝基芴酮(2-MNF)、2,7-二硝基芴酮(2,7-DNF)、2,4,7-三硝基芴酮(2,4,7-TNF)和2,4,5,7-四硝基芴酮(2,4,5,7-TeNF)作为N-VCz的热诱导电荷转移聚合反应的引发剂,并找出了聚合产率与引发剂的用量、引发剂的电子亲合势和N-VCz-引发剂络合平衡常数之间的关系。
N-vinylcarbazole (N-VCz) is a strong electron donor, it is easy for charge-transfer polymerization. So in recent years a lot of research on it. However, the use of similar compounds as initiators for system studies has reported very little. We have prepared 2-nitrofluorenone (2-MNF), 2,7-dinitrofluorenone (2,7-DNF), 2,4,7-trinitrofluorenone (2,4,7- TNF) and 2,4,5,7-tetranitrofluorenone (2,4,5,7-TeNF) as initiators for the thermal induced charge-transfer polymerization of N-VCz, and found that the polymerization yield and The amount of initiator, the electron affinity of the initiator and the equilibrium constant of N-VCz-initiator complexation.
