The investigation of the polymorphism of tri- and tetravalent phthalocyanine (Pc) species containing an axial ligand has been the focus of this work. The polymorphic nature of these nonplanar Pcs results in unique packing arrangements in the solid state, which affect the spectral and conductive properties of thin films generated with these materials. The goal of this work was to isolate and identify the various phases formed by vanadyl and chloro-gallium Pcs, establish a correlation between surface morphology, vibrational and absorption spectra and crystalline arrangement and further the understanding of the molecular structure of each phase. Block and platelet morphologies were observed for both Pc species. A correlation between the morphology and several phase sensitive peaks in the vibrational and visible absorption spectra was established. It was shown that the block/prism morphology corresponds to a cofacially bridged structure and the platelet phase consists of a slip-stacked arrangement.
