Abstract

The present invention relates to a method for improving the hole injection ability of ITO transparent conductive film, which comprises the following steps: S1, adding one or two compounds of the structure shown in the structural formula (I) in the solvent ultra-dry benzene solution, said The volume ratio of the compound to the solvent ultra-dry benzene solution is 0.1%-5%, and they are fully mixed; S2, after treating the surface of the ITO transparent conductive film by UV light, soak the surface of the ITO transparent conductive film in the mixed solution prepared in step S1 ; S3, taking out the ITO transparent conductive film soaked in step S2, ultrasonically removing impurities in an alcohol solution, and drying to obtain an ITO transparent conductive film with high hole injection capability.

Description

Technical field [0001] The invention belongs to the technical field of conductive film surface treatment, and specifically relates to a method for improving the hole injection capability of an ITO transparent conductive film and its application in an organic electroluminescent device. Background technique [0002] Indium tin oxide (English full name Indiumtinoxide, abbreviated as ITO) transparent conductive film not only has excellent electrical conductivity, but also has a light transmittance of 90%, with transparent characteristics; it is widely used as an organic electroluminescent device (English full name is OrganicLight -EmittingDiode, abbreviated as OLED), liquid crystal display devices (English full name Liquidcrystaldisplays, abbreviated LCD), organic photovoltaic cells (English full name OrganicPhotovoltaic, abbreviated as OPVs) and other devices can also be used as light-transmitting windows. [0003] In addition to its dominant position in the flat panel display field, ...
