Özet

In this study, the new [3,5-bis(2-morpholin-4-ylethoxy)phenyl]methanol 3 has been synthesized. Then novel axially di-substituted silicon phthalocyanine 3, axially mono-substituted subphthalocyanine 5 and their quaternized derivatives 4a and 5a have been synthesized using a convenient route starting with the [3,5-bis(2-morpholin-4-ylethoxy)phenyl]methanol. The complexes are obtained in high yield and are soluble in many organic solvents. The aggregation behavior of axially di-substituted silicon phthalocyanine 3, axially mono-substituted subphthalocyanine 5 and their quaternized derivatives 4a and 5a was examined in different solvents. The effect of solvents on absorption spectra was studied in various solvents. In all studied solvents, these complexes were non-aggregated. The electrochemical properties of axially di-substituted silicon phthalocyanine 3 and axially mono-substituted subphthalocyanine 5 were also investigated by cyclic voltammetry and square wave voltammetry techniques. Cyclic voltammetry revealed two reduction couples and one oxidation couple for 4 and 5. (C) 2015 Elsevier B.V. All rights reserved.
