基于聚乙烯醇缩丁醛(PVB)基质中光碱生成物的光解作用，设计了一种荧光成像系统。合成了以丙基和苯乙基为基团，邻苯二甲酰亚胺、琥珀酰亚胺、二-2-噻吩酮亚氨基和二苯甲酮亚胺为光敏基团的光碱产生剂。详细考察了两个离开基团和四个光敏物种对光化学行为的影响。结果表明，这些光碱发生器的光化学性质依赖于光敏物种，而不是离开基团。进一步的研究表明，琥珀酰亚胺丙基氨基甲酸酯(SPRC)在所有光碱产生剂中具有最好的热稳定性和较快的光解速率。因此，采用包埋了SPRC的PVB薄膜作为荧光成像材料。经荧光胺处理的PVB薄膜得到的图案化荧光图像显示出明亮的绿色荧光，这为光存储或彩色电子显示提供了潜在的应用。(C)2014年威利期刊公司。
A fluorescence imaging system is designed based on the photodecomposition of photobase generators embedded in polyvinyl butyral (PVB) matrix. These photobase generators were synthesized with propyl and phenethyl units served as leaving groups, and phthalimido, succinimido, di-2-thienyl ketoximino, and benzophenoneoximino units acted as photosensitive species, respectively. The influences of the two leaving groups and four photosensitive species on the photochemical behavior were investigated in detail. The results demonstrate that the photochemical properties of these photobase generators depend on the photosensitive species other than the leaving groups. And further study shows that succinimido propylcarbamate (SPrC) exhibits the best thermal stability and relatively quick rate of photodecomposition among all the photobase generators. Therefore, a PVB film embedded with SPrC is used as a fluorescence imaging material. The patterned fluorescence image obtained from the fluorescamine-treated irradiated PVB film showed bright green fluorescence, which provides potential application for optical storage or color electronic displays.
