NOVELTY - Use of platinum-dicyano-bisisocyanide complexes (I) in an organic electronic device for emission or absorption of light in the spectral range of 400-500 nm (blue light), is claimed.    USE - (I) are useful: in an organic electronic device for emission or absorption of light in the blue light region; in organic electronic device for the emission of light in the blue light region and/or for absorption of light in ultraviolet and blue spectral region; as charge transport material and also as a light emitter; for generating light in the blue spectral range, preferably in the wavelength range of 400-500 nm, preferably having emission maxima of 430-480 nm; and for producing organic electronic device comprising organic LED, light emitting electrochemical cells, organic LED sensors, preferably not hermetically to the outside shielded gas and vapor sensors, organic solar cells, organic field effect transistors, organic lasers, organic diodes, organic photodiodes or down conversion systems (all claimed).    ADVANTAGE - (I) exhibit improved singlet-harvesting and blue light emitting effect.    DETAILED DESCRIPTION - Use of platinum-dicyano-bisisocyanide complexes of formula (NC-Pt((CN-CH(R1)-CH 2-CH(R2)-R3) 2)-CN) (I) in an organic electronic device for emission or absorption of light in the spectral range of 400-500 nm (blue light), is claimed.
