Novel phenyl- and phenoxy-substituted subphthalocyanines bearing a halogen ion in the axial position were synthesised. The compounds obtained were characterised by 1H, 13C and 1H-1H nuclear Overhauser effect spectroscopy and high resolution mass spectrometry. The correlation between the position of the Q-band and the nature of axial or peripheral substituents was shown. Redox transitions of the compounds were characterised using cyclic voltammetry in o-dichlorobenzene. The redox potentials determined suggest a higher electron-donating ability of phenyl substituents compared to phenoxy groups. Absorption cross sections, quantum yields of fluorescence and intersystem crossing, lifetimes of excited states and non-linear optical properties were studied using UV-Vis spectroscopy, stationary and time-resolved fluorimetry, and a non-linear Z-scan technique.
