通过将聚集诱导发射 (AIE) 分子 4,4'-(肼-1,2-二亚基双(亚甲基)) 双(3-羟基苯甲酸) (HDBB) 封装到沸石咪唑酯骨架-8 (ZIF-8) 的纳米通道中，开发了 HDBB@ZIF-8 荧光探针，用于区分小醇溶剂分子。 HDBB分子封装后ZIF-8的晶体结构和形貌保持良好。将HDBB封装到ZIF-8的受限纳米空间中不仅引发了新的绿色荧光发射，而且赋予了它们独特的碳链长度依赖的醇荧光强度，这是在纯HDBB和ZIF-8中未观察到的。该特性可归因于宿主 ZIF-8 的醇-水吸附选择性。此外，这些复合材料的荧光强度与乙醇浓度之间存在较宽的线性范围的线性关系，可以用作化学传感器来检测真实葡萄酒样品中的乙醇含量。
A HDBB@ZIF-8 fluorescent probe has been developed by encapsulating the aggregation-induced emission (AIE) molecule 4,4’-(hydrazine-1,2-diylidenebis(methanylylidene)) bis(3-hydroxybenzoic acid) (HDBB) into the nanochannels of zeolitic imidazolate frameworks-8 (ZIF-8) for distinguishing small alcohol solvent molecules. The crystal structure and morphology of ZIF-8 are well maintained after the encapsulation of HDBB molecules. Encapsulation of HDBB into the confined nanospace of ZIF-8 not only triggered new green fluorescent emission but also endowed them with unique carbon chain length-dependent fluorescence intensity for alcohols, which has not been observed in pure HDBB and ZIF-8. This property could be attributed to the alcohol–water sorption selectivity of host ZIF-8. Moreover, a linear relationship is obtained between the fluorescent intensity of these composites and the concentrations of ethanol with a wide linear range, which could be employed as a chemosensor to detect the content of ethanol in the real wine sample.
