This paper describes the synthesis and spectroscopic characterisation of a range of new axially disubstituted silicon phthalocyanines, with 4-{2-[3-(diethylamino)phenoxy]ethoxy}, 4-(1,4,7,10-tetraoxacyclododecan-2-ylmethoxy) and 4-(1,4,7,10,13,16-hexaoxacyclooctadecan-2-ylmethoxy) groups as axial ligands. These axially disubstituted silicon phthalocyanine complexes were synthesised for the first time here. The newly synthesised silicon phthalocyanines were characterised by ultravioletvisible, infrared, proton and carbon nuclear magnetic resonance spectroscopy, electrospray ionisation mass spectrometry and elemental analysis. The aggregation behaviour of these compounds was investigated in different concentrations of chloroform and the effects of various organic solvents on the absorption spectra were studied.
