A novel fluorescent Probe <b>1</b>, based on phenanthro-imidazole has been developed as an efficient chemosensor for the trace detection of copper ions (Cu<sup>2+</sup>). Probe <b>1</b> demonstrated sensitive fluorescence quenching upon binding with Cu<sup>2+</sup> through 1:1 stoichiometric chelation. The detection limit for Cu<sup>2+</sup> ions was projected through linear quenching fitting to be as low as 2.77 × 10<sup>-8</sup> M (or 1.77 ppb). The sensing response was highly selective toward ...[more]
