This contribution deals with the patterned immobilization of a highly luminescent Ru(II) complex in thin polymer films. Photosensitive polymers bearing benzyl thiocyanate groups in the side chain undergo a photoisomerization reaction upon irradiation with UV light. This photoreaction leads to the formation of isothiocyanate groups, which readily react with primary amino groups. We report on the immobilization of a highly luminescent Ru(II) complex in the illuminated areas of a norbornene based polymer by means of this photoreaction. In combination with lithographic techniques, patterned, luminescent polymer films are realized. A novel approach for tuning the electroluminescence of polyfluorene‐based organic light‐ emitting diodes by the immobilization of this Ru(II) complex in the emission layer is suggested.
