摘要：

A new L-lysine derivative featuring an anthracene unit is synthesized and characterized by elemental analysis, ESI-MS, H-1-NMR, and C-13-NMR. It can selectively bind ATP in acidic aqueous solutions, and be used as a highly selective fluorescent chemosensor for Cu2+ at neutral pH, resulting in fluorescence quenching. According to these characters, two combinational logic circuits are fabricated on a single molecule with three chemical inputs [H+(IN1), OH-(IN2), ATP(IN31)] and [H+(IN1), OH-(IN2), Cu2+ (IN32)], respectively.
