摘要：
A new fluorescent chemosensor comprising anthracene and indanedione-based Michael receptor, which recognizes cyanide anion with high selectivity was designed and synthesized. The Michael addition of cyanide to the chemosensor elicits a fluorescence enhancement at a longer wavelength, which constituted the signature for cyanide detection. The mechanism of exciplex formation was proposed for the interesting observation.
