An organic electronic device of the present invention includes a substrate, at least two electrodes formed on the substrate, a conductive organic thin film that is formed on the substrate and electrically connects the electrodes, and a coating film for coating at least a portion of the electrodes. The conductive organic thin film is a polymer of organic molecules containing a conjugated-bondable group, and one end of each of the organic molecules is chemically bonded to the surface of the substrate and the conjugated-bondable groups in the organic molecules are polymerized with other conjugated-bondable groups to form a conjugated bond chain. The coating film electrically connects the electrodes to the conductive organic thin film and achieves a smaller connection resistance than that in the case where the electrodes and the conductive organic thin film are connected directly. As the coating film, a film made of metal selected from gold, platinum, and silver, a conductive polymeric film, or a monomolecular film that is chemically bonded to the electrodes can be used.
本发明的有机电子器件包括基板、至少两个形成在基板上的电极、形成在基板上并电性连接电极的导电有机薄膜,以及用于涂覆至少一部分电极的涂层膜。导电有机薄膜是含有共轭键合团的有机分子的聚合物,每个有机分子的一端化学键合在基板表面上,有机分子中的共轭键合团与其他共轭键合团聚合形成共轭键链。涂层膜将电极与导电有机薄膜电性连接,并实现比电极和导电有机薄膜直接连接时更小的连接电阻。涂层膜可以是由金、铂、银等金属制成的膜、导电聚合物膜或化学键合在电极上的单分子膜。
