Abstract
A novel chromogenic and fluorogenic dye chemosensor was computationally designed using MO theory calculation and synthesized based on donor-π-acceptor unit. This prepared dye sensor showed the selective Ni2+ metal ion sensing effects in optical properties with UV-vis absorption and fluorescence emission. Dye sensor displayed evident absorption changes with Ni2+ ion and highly selective fluorescence quenching effect was determined. But it showed no significant changes upon the addition of other metal ions such as Cd2+, Na2+, Mg2+, Pb2+, Fe2+, Fe3+, Ca2+, Cu2+, Hg2+ and Zn2+
