Abstract This work describes the study of photophysical properties of triazolelinked benzothiazole based Silane (K3) and its nanoparticles (K3‐NPs). Interestingly, both K3 and K3‐NPs exhibited highly selective chemo‐sensing ablility for Cu 2+ ions. The significance of N, S and triazole group in synthesized compounds for Cu 2+ sensing has been confirmed by structure‐property studies. Concentration dependent colorimetric metal sensing studies indicate that Cu 2+ can be detected up to 10 μM. DFT studies, colorimetric analysis, Cyclic Voltametry, absorption and emission spectroscopy techniques helped us to evaluate efficiency towards amino acids along with copper complexation.
