CHARGE-TRANSPORTING VARNISH FOR SPRAY OR INKJET APPLICATION |
摘要 |
Disclosed is a charge-transporting varnish containing a charge-transporting organic material, a good solvent, at least one poor solvent with high leveling properties, and at least one volatile poor solvent. The charge-transporting organic material is composed of a charge-transporting material consisting of a charge-transporting monomer or a charge-transporting oligomer having a number average molecular weight of 200 to 5000, or alternatively composed of such a charge-transporting material and an electron-accepting dopant material or a hole-accepting dopant material. This charge-transporting varnish enables to form a uniform and smooth charge-transporting thin film by a spray method or an ink jet method on an exposed electrode portion such as ITO or IZO of a substrate on which a structure of a simple or complicated pattern is formed beforehand. |
