Peripherally alphas-substituted novel phthalocyanines

摘要

Two novel,nickel phthalocyanines bearing peripherally alpha(alpha)-substituents,namely octa(1,3-bis(dodecyloxy)propan-2-ol)and octa(1,3-bis[2-(2-ethoxyethoxy)ethoxy]propan-2-ol)were synthesized by cyclotetramerisation of the corresponding nitriles.At room temperature,the peripherally alpha-substituted Ni(II)phthalocyanine complexes exhibited a relatively viscous liquid state;their spectroscopic properties and aggregation behaviour were investigated in different solvents and at different concentrations in chloroform.The two compounds showed Q-bands in the near-IR region of the electronic spectrum and did not aggregate in all solvents and under a wide range of concentrations in chloroform.
