摘要： 研究了7种不同芳烃结构的芳茂铁四氟硼酸盐作为阳离子紫外光聚合和光固化引发剂在环氧体系中的光引发活性,其中[C5H5Fe2,5-(CH3)2CO-C6H3]BF4(Ⅵ)和[CH3CO-C5H4Fe2,4-(CH3)2-C6H4]BF4(Ⅶ)为新物质.研究发现,这7个芳茂铁四氟硼酸盐在370和450nm附近均有较强吸收;芳环上引入共轭CC和共轭CO使吸收峰发生红移,且使摩尔消光系数和感光速度均有所提高,更适合于以高压汞灯为辐射光源的长波紫外固化;芳茂铁四氟硼酸盐可以引发环氧树脂、脂环族和脂肪族缩水甘油基环氧单分子,通过加热或使用有机过氧化物[如过氧化苯甲酰(BPO)]可明显提高环氧化合物的聚合速度.

Abstract: The photosensitivity in the expoxide system of several arene cyclopentadienyl iron tetroflouroborate salts with different structures was studied. Among them, [C5H5Fe2,5 (CH3)2CO-C6H3]BF4 and [CH3CO-C5H4Fe2,4 (CH3)2 C6H4]BF4 are new compounds. The study shows that all the salts have two main absorptions near 370 and 450 nm. It also shows that those with CC group and CO group have a stronger absorption and higher photosensitivity, and can be suitable for the light cured reaction irradiated by high pressure mercury lamp. Meanwhile, the study also shows that some kinds of organic expoxides including multifunctional epoxy resins, cycloaliphatic epoxides and glycidylethers can be initiated by these salts. Heating or adding BPO could prompt the rate of polymerization significantly.

Key words: Arene cyclopentadienyl iron tetroflouroborate salts, Cationic photoinitiator, Photosensitivity
