ABSTRACT:
A simple, flexible, convenient method for making silicon phthalocyanines and naphthalocyanines by inserting silicon into metal-free phthalocyanines and metal-free naphthalocyanines is provided. The method comprises: providing a metal-free phthalocyanine or metal-free naphthalocyanine; reacting the metal-free phthalocyanine or metal-free naphthalocyanine with HSiCl.sub.3 to provide a reaction product; then reacting the reaction product with water; and extracting a silicon phthalocyanine or a silicon naphthalocyanine. The invention also relates to novel phthalocyanines and naphthalocyanines. The phthalocyanines and naphthalocyanines are useful as photosensitizers and as dyes.
