Abstract

The present invention relates to a process for preparing highly pure tris-ortho-metallated organoiridium compounds and such pure organometallic compounds which may find use as coloring components in the near future as functional components (=functional materials) in a series of different types of applications which can be classed within the electronics industry in the widest sense.
