Methods for the preparation of three siloxysilicon naphthalocyanines, a siloxygermanium tetraphenoxynaphthalocyanine, a siloxysilicon tetra-t-butyl-naphthalocyanine, a cofacial double-ring siloxysilicon naphthalocyanine, and a cofacial triple-ring siloxysilicon naphthalocyanine that are relevant to the search for second generation PDT sensitizers are outlined. Ultraviolet-visible spectra, NMR spectra, and other properties of these compounds are given and discussed. In addition, an attempt to make an aluminum tetradibenzobarreleno-naphthalocyanine is described.© (1991) COPYRIGHT SPIE--The International Society for Optical Engineering.
