More Information
Summary:A composition containing at least one charge-transporting polymer compound having a crosslinking group and a weight-average molecular weight of 10,000 or more, at least one charge-transporting low-molecular compound having a crosslinking group and a molecular weight of 5,000 or less, and at least one aromatic organic solvent, the charge-transporting low-molecular-weight compound is a compound represented by formula (71) or the like. A method for manufacturing an organic electroluminescent element, the method comprising: a step for printing the composition by an ink jet method in a region partitioned by a liquid-repellent partition wall layer; a step in which the printed composition is vacuum-dried in a vacuum chamber to volatilize the organic solvent; and a step of baking the vacuum-dried composition at a high temperature. # imgabs0 # 一种组合物，包含：至少一种具有交联基且重均分子量为10,000以上的电荷传输性高分子化合物、至少一种具有交联基且分子量为5,000以下的电荷传输性低分子化合物，以及至少一种芳香族有机溶剂，所述电荷传输性低分子化合物为下述式(71)所表示的化合物等。一种有机电致发光元件的制造方法，包括：于由具有拨液性的间隔壁层划分出的区域，通过喷墨法印刷所述组合物的步骤
