A novel pyrene-based fluorescent chemosensor (pyren-1-ylmethyl)-L-valine (1) has been synthesized. 1 is a highly selective chemosensor for detecting Cu(II) ions through fluorescence quenching over other competitive metal ions and showing aqueous-organic solvent-based gelation properties. Rod-shaped surface morphology may be attributed to intermolecular Hydrogen bonding between the carboxylic acid group and π-π stacking of pyrene moiety. In addition, 1 can also be utilized for the practical detection of Cu2+ion in natural water samples.
