The electronic properties of series of mononuclear ortho-platinated and -palladated metallomesogens were investigated by means of UV-vis absorption and fluorescence spectroscopy in solution, fluorescence spectroscopy in the solid state as well as time-resolved photo-emf measurements. The organoplatinum compounds show luminescence in solution and in the solid state as well as photoconductivity caused by Pt center dot center dot center dot Pt closed shell interactions in comparison to the non-luminescent and non-photoconductive organopalladium compounds. A significant influence of the substitution pattern regarding luminescence and photoconductivity of the materials (number, length and distribution of attached alkyl chains) was found for the organoplatinum phenylpyrimidine and phenylpyridine series 1 and 3.
