Abstract
The present invention relates to chemical compounds that can be used in electrooptical applications. The electrically conductive and optical properties of these compounds, e.g. hole transporting, electron transporting and/or light emitting properties can be predetermined by substituting the core structure of these compounds with respective residues. The core structure (1) of the compounds according to the invention comprises two opposing aromatic moieties which are chemically bonded through an intermediate central atom. This central atom has a tetraedric configuration and therefore provides an orthogonal orientation to the organic moieties. ##STR00001##
