摘　　要：A simple-structured 4-（2-pyridylazo）resorcinol （PAR） system presents interesting properties with dual fluorescent outputs. Modulated by solution pH two kinds of reversible switch behaviors, ＂ON-OFF＂ and ＂OFF-ON＂, were realized with the PAR system. Stimulated by different combination of external stimulus, such as metal ions, UV ir- radiation and solution pH, the PAR system could perform multiple logic functions including three inputs AND, two inputs INHIBIT and combinatorial ＂NOR/AND＂ in parallel. The operation of the designed system is very simple and detected with a high sensitive fluorescent signal.A simple-structured 4-（2-pyridylazo）resorcinol （PAR） system presents interesting properties with dual fluorescent outputs.
