采用光子晶体技术和分子印迹技术结合的方法, 以双酚A为模板分子、甲醇为溶剂、甲基丙烯酸和丙烯酰胺为单体、乙二醇二甲基丙烯酸甲酯为交联剂、2,2-二乙氧基苯乙酮为光引发剂, 制备了具有三维有序排列大孔结构的双酚A分子印迹光子晶体凝胶膜。随着双酚A的含量从10-10 mol/L增加到10-3 mol/L, 布拉格衍射波长红移达36 nm, 肉眼可分辨出颜色变化, 且波长的变化不受离子强度和阿魏酸、水杨酸、对苯二酚等测定样品结构类似的干扰化合物的影响。

B2O3-P2O5-SiO2 (BPS) three-dimensional (3D) high-organized polystyrene (PS) opals and inverse opals with large domain were fabricated and characterized. Scanning electron microscope (SEM) shows three or four small "windows", indicating that a very well interconnection between PS spheres of opal. The ultraviolet-visible (UV-vis) spectra indicate that the photonic band gaps (PBGs) are about 710 and 604 nm for 320- and 270-nm spheres respectively. While according to Bragg's equation, the simulation results should be 762 and 643 nm, which mean that 52 and 39 nm were shifted to blue region, respectively.
