Abstract
Novel discotic liquid crystalline porphyrins and discotic liquid crystalline metal complexes, methods for their preparation, and device fabrication are disclosed. Materials with partially perfluorinated alkyl group in the peripheral chains show a strong tendency towards the formation of homeotropic alignment. These compounds are capable of being used as high-efficiency photovoltaic materials, organic semiconducting materials, and organic light emitting materials.
