A photonic crystal material based on β-cyclodextrin (β-CD) with adsorption capacity is reported. The materials ((A-β-CD)-AM PC) consist of 3D poly (methyl methacrylate) (PMMA) colloidal microsphere arrays and hydrogels supplemented with β-cyclodextrin modified by acryloyl chloride. The prepared materials are then utilized for VOCs gas sensing. The 3D O-(A-β-CD)-AM PC was used to detect toluene, xylene, and acetone and the response was seen as the red-shift of the reflection peak. The 3D I-(A-β-CD)-AM PC was used to detect toluene, xylene, and acetone which occurred redshifted, while methanol, ethanol, and propanol and the peaks' red-shifting was observed. However, among these, methanol gave the largest red-shift response The sensor has broad prospects in the detection of alcohol and the detection of alcohol-loaded drug releases in the future.
报道了一种具有吸附能力的基于β-环糊精（β-CD）的光子晶体材料。该材料（（A-β-CD）-AM PC）由三维聚甲基丙烯酸甲酯（PMMA）胶体微球阵列和补充有经丙烯酰氯改性的β-环糊精的水凝胶组成。然后将制备的材料用于挥发性有机化合物（VOCs）气体传感。三维O-（A-β-CD）-AM PC用于检测甲苯、二甲苯和丙酮，响应表现为反射峰的红移。三维I-（A-β-CD）-AM PC用于检测甲苯、二甲苯和丙酮，出现了红移，同时对甲醇、乙醇和丙醇也观察到了峰的红移。然而，其中甲醇给出的红移响应最大。该传感器在未来酒精检测和载酒精药物释放检测方面具有广阔前景。
