✦ Synopsis


The Photochromism of Fulgides. IX. Investigations of the Photochemistry of α‐3,5‐Dimethoxyphenyl‐δ,δ‐dimethylfulgide

The mechanism of photoisomerization of α‐3,5‐dimethoxyphenyl‐δ, δ‐dimethylfulgide was investigated by means of u.v./vis‐ and fluorescence spectroscopy. The quantum yields of E‐Z isomerization and cyclisation were determined in various solvents and at different temperatures. Triplet sensitization of E‐Z isomerization by several sensitizers has been found. The thermal dark reactions of the deep coloured species were reinvestigated.
