Light sensitive coumarinyl(thienyl)thiazole derivatives exhibiting photochromism and fluorescence were synthesized, characterized and their behavior was investigated theoretically using density functional theory (DFT). In presence of UV light, the molecules switch to the bridged cyclic isomeric form and on irradiation with visible light, they revert back to their original molecular form. These molecules are sensitive to both UV and visible light, and switch themselves between open ring isomers and closed ring isomers. The photo-regulated-switching energy (ΔE) from open to closed isomeric form is approximately 6.3 kcal/mol. All the synthesized derivatives exhibit fluorescence only in their open form. Theoretical data is compared with the experimental data and both show similar results.
