摘要:
以4,7-二甲基-1,10-邻菲罗啉(dmphen)和4,7-二苯基-1,10-邻菲罗啉(dpphen)为配体分别与三氯化铋反应,经常温挥发合成了2个新的配合物Bi2(dmphen)2Cl6(DMSO)2(1)和[Bi(dpphen)Cl4]·Hdpphen·DMF(2)。晶体结构分析表明,双核结构的配合物1中Bi(Ⅲ)离子配位数为7,显示为五角双锥构型,而单核的配合物2中Bi(Ⅲ)离子配位数为6,呈现为八面体构型。考察了所得配合物对催化ε-己内酯本体开环聚合的催化性能,结果表明,配合物1对该反应显示出较高的单体转化率、所得聚酯分子质量较高、分子质量分布较窄以及不同位次取代的己内酯底物都能适用于该催化体系。
Abstract:
Reaction of BiCl3 with 4,7-dimethyl-1,10-phenanthroline(dmphen)or 4,7-diphenyl-1,10-phenanthroline(dpphen)synthesized two new complexes Bi2(dmphen)2Cl6(DMSO)2(1)and [Bi(dpphen)Cl4]·Hdpphen·DMF(2), respectively. Complexes 1 and 2 displays dinuclear and mononuclear molecular structure types, where each Bi(Ⅲ)ion in 1 is seven-coordinated with a pentagonal bipyramidal geometry, while each Bi(III)ion in 2 shows a six-coordinated octahedral geometry. The results of catalytic experiments showed that 1 is more active than 2 towards bulk ring-opening polymerization of ε-caprolactones with high monomer conversion, giving polyesters with high molecular weights and narrow molecular weight distributions. Furthermore, the Bi(Ⅲ)complexes also exhibited catalytic activity for substituted ε-caprolactones in different positions.
