A two-photon fluorescent probe for Cu2+ based on dansyl moiety and its application in bioimaging

•A new fluorescent probe for detection of Cu2+ has been developed.•The probe sensitively and selectively responds to Cu2+ with remarkably weakened fluorescence intensity and red shift.•The probe can detect Cu2+ by one- and two-photon excited fluorescence with low detection limits (
