Inverse opal hydrogel films composed of hydroxyethyl 2-methacrylate and phenylboronic acid (IOHG_HEMA+3APBA) were prepared by a convenient ultrasonic-induced self-assembly method. The IOHG_HEMA+3APBA films had brilliant blue-violet color when they were immersed in deionized water and reached swelling equilibrium. The IOHG_HEMA+3APBA films were used as sensors to detect chemicals with similar structures. When the IOHG_HEMA+3APBA films were in contact with different monosaccharide, polysaccharide or polyhydric alcohol solutions, their reflection peaks maxima (λ_max) shifted over the entire visible wavelength range (520 to 780 nm). The red shift of λ_max was related to the number of effective hydroxyl groups and the molecular size of the detected molecules. Thus isomers or organic compounds with similar structures or properties may induce different λ_max shifts of the IOHG_HEMA+3APBA films.

通过方便的超声诱导自组装方法制备了由2-甲基丙烯酸羟乙酯和苯基硼酸组成的蛋白石水凝胶反相膜（IOHG _{HEMA + 3APBA}）。将IOHG _{HEMA + 3APBA}薄膜浸入去离子水中并达到溶胀平衡时，它们具有鲜艳的蓝紫色。IOHG _{HEMA + 3APBA}膜用作传感器来检测结构相似的化学物质。当IOHG _{HEMA + 3APBA}膜是在具有不同的单糖，多糖或多元醇溶液接触，它们的反射峰的最大值（λ_最大）偏移在整个可见光波长范围（520至780nm）。红移λ_最大与有效羟基的数量和检测到的分子的分子大小有关。因此异构体或具有相似的结构或性质的有机化合物可以诱导不同λ_最大的IOHG的位移_{HEMA + 3APBA}膜。
