具有光活性的1,1′-联-2-萘酚(BINOL)衍生物是近年来研究较多的C2轴不对称芳香化合物,不仅具有很强的手性诱导作用,而且在适合结构基团修饰下能产生很强的荧光,可作为一类有效而灵敏的荧光化学传感器。在与手性胺、氨基醇、氨基酸、α-羟基羧酸、手性醇和单糖等手性有机化合物作用时,该荧光化学传感器在不同识别位点接受客体分子、通过光诱导电子转移(PET)及电子交换能量转移(EET)等引起共轭高分子内能级发生变化,使得所有这些相互作用十分灵敏地在其发光强度和能量上反映出来,具体表现在化学传感器荧光增强与减弱或发射波长的变化上。本文总结了近年来1,1′-联-2-萘酚衍生物的荧光化学传感器在手性异构体识别领域的最新研究进展。
Chiral BINOL and its derivatives are one kind of the most important C2 symmetric compounds. The chiral fluorescent sensors based on optically active 1,1 '-bi-2-naphthol and its derivatives can be designed by strategic placement of substituents within the framework of a given BINOL derivative at the well-defined molecular level and used as excellent fluorescent chemosensors to chiral amines, amino alcohols, amino acids, a-hydroxycarboxylic acids, chiral alcohols and monosaccharides due to their unique chiral configuration and fluorescent property. In this paper, the recent progress of optically active 1,1 '-bi-2-naphthol and its derivatives as fluorescence chemosensors for chiral molecular recognition is summarized.
