Material for organic electroluminescence device and process for producing the same

摘要

An organic electroluminescence material is produced by bringing a source (1) containing at least an emission center-forming compound absorptive of a laser beam and defined in the predetermined pattern into contact with targets (2a, 2b) which is transmittable of the laser beam and has at least one function selected from an electron-transporting function and a hole-transporting function, and irradiating with the laser beam from the target (2) side to implant the emission center-forming compound (3) contained in the source (1) into the target (2a). The organic electroluminescence device thus obtained has emission centers in the area corresponding to the pattern of the source. The source may be constituted solely of the emission center-forming compound. The present invention provides an organic EL material susceptible of fine patterning, a process for producing the same, and an organic EL device using the same. <IMAGE>
