A process for producing for a material for an organic electroluminescent device having an emission center comprises irradiating a laser beam to implant an emission center-forming compound constituting a source into a target having at least one function selected from an electron-transporting function and a hole-transporting function. According to the process, the laser beam and at least the target are relatively moved with irradiating the beam to form the emission center with a predetermined pattern. Moreover, the source and the target being in contact with each other may be moved relative to the laser beam for forming the emission center with a predetermined pattern. Further, the emission center at an area, corresponding to an interference pattern of an interference light, of the target may be formed by irradiating the interference light of the laser beam.

Material for organic electroluminescent device and its manufacturing method

Nitrogen-containing heterocyclic compound and electroluminescent device

An organic electroluminescence device material having emission centers is formed by bringing a source ( ) containing an emission center-forming compound absorptive of laser beams into contact with a target ( ) having at least one function selected from an electron-transporting function and a hole-transporting function, and irradiating a laser beam at an intensity of or below the ablation threshold value of the source ( ) from the source ( ) side (or the target ( ) side) thereby to implant the emission center-forming compound ( ) of the source ( ) into the target ( ). Thus, it is possible to make a fine and minute pattern on the organic electroluminescence device material.
