Abstract
D–π–A chalcone composed of pyrene and thiophene units wassynthesized and characterized. The solvatochromic response wasinvestigated in different solvents of various polarities. Additionally, theinclusion characteristic of the investigated dye was studied in differentorganized assemblies of three surfactants. The spectral changessuggested the chalcone would be useful to study the critical micelleconcentrations of the studied assemblies systems. Furthermore, theabsorption and emission spectra are sensitive towards H+, Co2+, Ni2+,Cd2+, Pb2+, and Zn2+ owing to acido- and metallo-chromic behaviors.These results suggest that the investigated chalcone would be potentialcandidate for polarity sensors, probes to characterize microenviromentalpolarity of the surfactants, and sensors for metal ions and H+ proton.
