Abstract
A new highly selective fluorescent chemosensor for Nickel ion was developed based on pyrene-conjugated pyridine. The ratiometric sensing of Nickel ions by the chemosensor in solution is by the formation of a monomer-excimer emissions. It’s a reversible sensor and has a detection limit up to micro molar level. All the findings were supported by the DFT studies. In addition, ratiometric fluorescent changes upon the addition of nickel ions, is also applied in cell imaging.
