摘要：

The title compound, beta-tetrakis(2,3,4,5,6-pentaphenylbenzene) phthalocyanine, was prepared by cyclotetramerization of 4-(2,3,4,5,6-pentaphenylbenzene)phthalonitrile, in the presence of hydroquinone. The phthalonitrile derivative was synthesized by a Diels-Alder reaction between 4-(phenylethynyl)phthalonitrile and tetracyclone. This methodology was also extended to alkoxy (butyloxy and dodecyloxy)-substituted polyphenylated phthalocyanines and metallophthalocyanines. The polyphenylated design renders the Pcs soluble in common organic solvents. degenerate four-wave mixing studies of the phthalocyanine in dioxane gave X-(3) = 0.52 x 10(-10) esu and (gamma) = 6.12 x 10(-32) esu, measured at 1064 nm.
