Synthesis of porphyrins with reactive groups on phenyl rings. 8. Azo dyes on tetraphenylporphyrins

Article abstract of DOI:10.1007/BF01176963

Porphyrins having covalently attached residues of azo dyes on the periphery of the molecule have been synthesized by the diazotization of tetraaminophenylporphyrins and subsequent azo coupling of the diazonium salts with phenol, and with α- and β-naphthols. The possibility of π - π electron interaction of the two chromophoric systems has been studied. 1997 Plenum Publishing Corporation.
