摘要

•New derivatives of Xanthene dyes (BFFNH) was prepared and fully characterized.•The prepared compound showing high selectivity and sensitivity in micro-mole to Cu+2.•The BFFNH considered as a duel functional chemosensor to heavy metal and pH.•Thermodynamics and kinetics study of the coordinated sensor was investigated.•The application of BFFNH for monitoring of Cu2+ ions in water was studied.
