摘      要：A new two-photon absorption compound, 2-{4-[（dicyanomethylidene-5,5-dimethylcyclohexl）vinyl]phenyl}imidazo[4,5- f][1,10]phenanthroline （DDVPIP）, was synthesized and characterized. The one-photon excited fluorescence （OPEF） and two- photon excited fluorescence （TPEF） of DDVP1P are sensitive to the acid/base of the solution, which are enhanced in basic solution but weakened in acidic solution. Charge-transfer （CT） states of DDVPIP were calculated through theory methods to explain its acid/ base-sensitive fluorescent properties.
