The invention relates to neutral mononuclear copper (I) complexes for emitting light and with a structure according to formula (A) in which: M represents: Cu(I); L∩L represents: a single, negatively charged, bidentate ligand; N∩N represents: a diimine ligand (substituted with R and FG), in particular a substituted 2,2′-bipyridine derivative (bpy) or a substituted 1,10-phenanthroline derivative (phen); R represents: at least one sterically demanding substituent for preventing the planarisation of the complex in the excited state; FG=functional group, and represents: at least one second substituent for increasing solubility in organic solvents. The substituent can also be used for electron transport or alternatively for hole transport, said functional group being bound to the diimine ligands either directly or by means of suitable bridges; and the copper (I) complex: having a ΔE(S1−T1) value of less than 2500 cm−1 between the lowest excited singlet state (S1) and the triplet state (T1) which lies below; having an emission lifespan of at most 20 μs; having an emission quantum yield of greater than 40%, and a solubility of at least 1 g/L in organic solvents, in particular polar organic hydrocarbons such as acetone, methyl ethyl ketone, benzene, toluene, chlorobenzene, dichlorobenzene, dichloromethane, chloroform, dichloroethane, tetrachloroethylene, alcohols, acetonitrile or water.

The invention relates to the use of a platinum-dicyano-bisisocyanide complex cluster, having a small ΔE distance, in particular between 500 cm−1 and 3000 cm−1, between the lowest triplet state and the overlying singlet state that is populated by means of thermal repopulation from the triplet, in an organic-electronic device for emission of blue light and for absorption in the ultraviolet and blue spectral range. The invention also relates to the use of the singlet harvesting method. Furthermore, the invention relates to the use of the high degrees of absorption of such platinum-dicyano-bisisocyanide complex clusters.
