Synthesis of Unsymmetrical Alkyloxy/Aryloxy-azaphthalocyanines Based on a Transetherification Reaction
2011
Abstract
Synthesis of unsymmetrical aryloxy substited azaphthalocyanines was presented for the first ime. The method employs a side reaction that occurs during cyclotetramerization - a transetherification of peripheral substituents.
New compounds were characterized also from the point of view of photophysical and photochemical properties and showed good quantum yields of fluorescence and singlet oxygen.
