摘要：

A new 8-hydroxyquinoline-based chemosensor possessing a semirigid structure was designed, and its fluorescent sensing behavior toward metalions was investigated. A prominent fluorescence enhancement only for Cd2+ was found in aqueous methanol solution. The results clearly suggest that the specific semirigid structure could selectively accommodate Cd2+ according to ionic radius, which would effectively suppress the intramolecular radiationless transitions from the n pi* state to enhance the fluorescence response.
