Abstract

The present invention relates to an organic electronic device comprising at least one inverse coordination complex, the N inverse coordination complex comprising: (i) a core consisting of one atom or of a plurality of atoms forming together a covalent cluster; (ii) a first coordination sphere consisting of at least four electropositive atoms having each individually an electronegativity according to Allen of less than 2,4; and (iii) a second coordination sphere comprising a plurality of ligands; wherein the first coordination sphere is closer to the core than the second coordination sphere; and all atoms of the core have a higher electronegativity according to Allen than any of the electropositive atoms of the first coordination sphere and a method for preparing the same.
