The unique monomer and excimer fluorescence emissions of pyrene were first exploited as distinctly photophysical signals to identify the possible diastereomers of guests within nor-seco-cucurbit[10]uril (NS-CB[10]) cavities. Further experiments revealed that balancing the hydrophilic and hydrophobic effects of the guest in aqueous solution can improve the molecular recognition and binding ability of NS-CB[10].
利用
吡啶的独特单体和激聚体荧光发射作为明显的光物理信号,首次用于识别位于
--cucurbit[10]uril (NS-CB[10])腔内可能存在的客体的可能对映异构体。进一步的实验表明,在水溶液中平衡客体的亲水性和疏水性效应可以提高NS-CB[10]的分子识别和结合能力。
