Concerning meso-tetraphenylporphyrin purification
Treatment of crude meso-tetraphenylporphyrin with 2,3-dichloro-5,6-dicyanobenzoquinone affords a high recovery of 'chlorin-free' meso-tetraphenylporphyrin (1), the excess of quinone and its transformation products being easily removed by adsorption on alumina. This new procedure is also applied to the purification of meso-tetraphenylporphyrin metal complexes.
