Photophysical Behavior and Sensing Response of Chalcone analogue containing pyrene moeity

Abstract

D-π-A chalcone composed of pyrene and thiophene units was synthesized and characterized. The solvatochromic response was investigated in different solvents of various polarities. Additionally, the inclusion characteristic of the investigated dye was studied in different organized assemblies of three surfactants. The spectral changes suggested the chalcone would be useful to study the critical micelle concentrations of the studied assemblies systems. Furthermore, the absorption and emission spectra are sensitive towards H + , Co 2+ , Ni 2+ , Cd 2+ , Pb 2+ , and Zn 2+ owing to acido-and metallo-chromic behaviors. These results suggest that the investigated chalcone would be potential candidate for polarity sensors, probes to characterize microenviromental polarity of the surfactants, and sensors for metal ions and H + proton.
