<p>It is intended to form an electrode pattern of organic device with free morphology and with high precision without being placed under various restraints accompanying the steps of metal mask preparation, formation of overhanging line bulkhead, detachment with adhesive film, etc. There is provided a process for producing an organic electronic device wherein voltage is applied to a layer of organic electronic material to thereby cause the same to function, which process comprises forming a foundation layer containing an optionally substituted 1,2-diarylethene, realizing an isomerization reaction in given pattern of the 1,2-diarylethene of the foundation layer, and thereafter applying an electrode material on the foundation layer to thereby form an electrode pattern corresponding to the given pattern. The adherence of magnesium, etc. as the electrode material is changed by the isomerization reaction of the 1,2-diarylethene, and further by the induction of the isomerization reaction, a striking difference between magnesium adherence and nonadherence is brought about when the ratio between open-ring molecules and closed-ring molecules at relevant portion exceeds a certain value. Thus, patterning can be accomplished.</p> |
