聚合物薄膜中的双色荧光微图案是通过使用一组含有邻苯二甲酰亚胺氨基甲酸酯基团的新型光产碱剂制备的。通过检测聚甲基丙烯酸缩水甘油酯的 pH 值、荧光强度和光交联的变化，研究了邻苯二甲酰亚胺氨基甲酸酯的光产碱作用。模型化合物的产物分析表明胺基团是由邻苯二甲酰亚胺氨基甲酸酯基团的C-N键的光解裂解产生的。将含有邻苯二甲酰亚胺氨基甲酸酯基团的共聚物应用于双色荧光成像材料。通过用荧光胺和罗丹明连续处理通过光掩模用254nm紫外光照射的共聚物膜，获得红黄色荧光微图案。通过改变激发波长，可以在单个聚合物薄膜上获得各种彩色荧光微图案 - 绿色、红色或红黄色。
Bicolor fluorescent micro-patterns in the polymer film are prepared through the use of a new group of photobase generator containing phthatimido carbamate groups. The photobase generation from phthalimide carbamates is studied by examining the changes in pH, fluorescence intensity, and photo-crosslinking of poly(glycidyl methacrylate). The product analysis of a model compound indicates that amine groups are produced from the photolytic cleavage of the C-N bond of the phthalimide carbamate groups. A copolymer containing phthalimide carbamate groups is applied to a bicolor fluorescent imaging material. Red-yellow fluorescent micropatterns are obtained by treating the copolymer film, which is irradiated with 254 nm UV light through a photomask, with fluorescamine and rhodamine, consecutively. Various colored fluorescent micropatterns - green, red, or red-yellow, are obtained on a single polymer film by varying the excitation wavelength.
