Document Type and Number:
WIPO Patent Application WO/2010/058777
Kind Code:
A1
Abstract:
Disclosed are a charge transporting material that contains a charge transporting substance, e.g., an oligoaniline compound, etc., and a heteropoly acid compound, e.g., phosphomolybdic acid, etc., as an electron-accepting dopant, and a charge transporting varnish that contains this charge transporting material and an organic solvent, wherein the charge transporting material is dissolved in the organic solvent. It is thus possible to provide a charge transporting material, which contains an electron-accepting dopant with high solubility in organic solvents, high oxidizing ability toward electron transporting host substances in a hole injection layer, and oxidizing ability toward hole transporting materials, and a charge transporting varnish, which contains this charge transporting material.
