M. Autret et al., INTRAMOLECULAR FLUORESCENCE QUENCHING IN AZOBENZENE-SUBSTITUTED PORPHYRINS, Journal of the Chemical Society, Chemical Communications, (10), 1994, pp. 1169-1170
Azobenzene-substituted porphyrins have been synthesised by condensatio
n of aminophenylporphyrins and nitrosophenyl derivatives; intramolecul
ar fluorescence quenching is detected in the ortho position;
