For the purpose of target syntheses of new photochromic compounds, a relationship between the structure and properties of a series of the known thermally irreversible photochromes was analyzed using the spectral kinetic data obtained by the authors.

A new fluorescence switch based on a photochromic diarylethene and a rhodamine B dye was designed and constructed successfully. With carefully selected components, the absorption band of the ring-closed photochromic diarylethene well overlapped with the emission band of the rhodamine B. The fluorescence emission intensity of rhodamine B is easily modulated with the photoisomerization of diarylethene
