Abstract

A series of novel tetra-substituted naphthalocyanines featuring hydroxy and carboxylate substituents in peripheral positions have been synthesised in reasonable yields and characterised by spectroscopic techniques. The photochemical properties of the tetra-acid derivative 7 were examined following immobilisation on a nanocrystalline TiO2 surface and photoinduced dye cations were observed following optical excitation. 7 has a redox ...
