Novel Photoswitchable Dihetarylethenes Exhibiting Fluorescence.

K Mahesh1, D Annapurna Padmavathi2.   

Abstract

Photochromic bridged dihetarylethenes exhibiting photochromism were synthesized. The synthesized coumarinyl(thienyl) thiazoles also display light regulated fluorescence in their open form. When the open form is irradiated with UV-light of wavelength less than 400 nm, a significant decrease in fluorescence intensity is observed due to cyclisation. Again, when the cyclised isomeric form is irradiated with visible light of wavelength greater than 470 nm the open form along with fluorescence is recovered. This reversible photo switching behaviour of dihetarylethenes may make them to be used as photo regulators. This phenomenon is also supported by DFT calculations.
