Paper Abstract

Five new photochromic unsymmetrical diarylethenes bearing different substitutes have been synthesized. Substituent effects on their optoelectronic properties, including photochromism, fluorescence properties were investigated in detail. The strong electron-donating substituents have effective contributions to the absorption maxima of the closed-ring isomers and the molar coefficients, while the electron-withdrawing substituents can shift significantly the absorption maxima of the diarylethenes to a longer wavelength and increase their cyclization quantum yield. In addition, these diarylethenes exhibited different color (red, purple, blue and green) both in solution and in PMMA film with alternating irradiation by UV/vis light, which can be potentially applied in the devices of full-color display.
