Synthesis and Solution Spectral Properties of Antimony(III) Phthalocyanine and Dihydroxoantimony(V) Phthalocyanine Complexes

A straightforward synthesis of (phthalocyaninato)antimony(III) fluoride and the corresponding dihydroxoantimony(V) phthalocyanine complex is reported. Both low- and high-valent compounds are well soluble in polar media without aggregation. The redox properties and the electronic absorption as well as luminescence spectra of these metalloid phthalocyanines are investigated for the first time in some detail.
