Abstract

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⋯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.
