METAL COMPLEXES HAVING VARIABLE EMISSION COLOURS FOR OPTOELECTRONIC DEVICES

摘要

The invention relates to a method for increasing the Stokes shift of an emitting metal complex having a given geometry in the region of the metal center in the electronic ground state, wherein said geometry is changing as a result of an optical excitation or an excitation by a hole-electron recombination, and to a polymeric matrix by means of which it is possible to influence the change in geometry in the excited state.
