Shifting the emission wavelength of a metal complex emitting in a given wavelength, to a wavelength which is greater than the given wavelength, useful in e.g. organic diodes, comprises embedding the metal complex into a polymer matrix

摘要

Shifting the emission wavelength of a metal complex emitting in a given wavelength, to a wavelength which is greater than the given wavelength, where the metal complex has a given geometry in the region of metal centre in the electronic ground state and an altered geometry in the electronic excited state, comprises embedding the metal complex into a polymer matrix, which allows the change of given geometry. An independent claim is included for a composition comprising the emitting metal complex and the polymeric matrix.
