A new guiding principle towards the spectral design of organic functional molecules

Abstract

A molecular orbital (MO) study on organic functional molecules was presented. The thermal stability of diarylethene and spironaphtoxazine was investigated. Then the optical properties, absorption wavelengths and intensities, of functional dyes were examined. The role of configuration mixing was emphasized. Finally, unexpected dependence of quantum yield on the wavelength was studied in the photochemical ring opening reaction of diarylethene. © 1996, Walter de Gruyter GmbH, Berlin/Boston.
