摘要:
Disclosed is a patterned substrate having a conductor pattern. The conductor pattern is obtained by forming a layer (B) containing an organic polysilane on a conductive substrate (A), irradiating a certain region of the layer (B) with a radiation for oxidizing the organic polysilane constituting the layer (B) in the certain region, and then applying a solution containing a conducting polymer, water and/or a hydrophilic solvent over at least the certain region of the layer (B) for forming a layer (C) composed of the conducting polymer while impregnating the layer (B) in the certain region with the conducting polymer for electrically connecting the layer (C) and the substrate (A).

摘要:
A methylol compound having a specific formula such that two triphenylamine groups each having two methylol groups are connected with each other by an oxygen atom, a methylene group, a vinylene group, or an ethylene group. The methylol compound is preferably prepared by subjecting a corresponding aldehyde compound to a reduction reaction in the presence of a reducing agent. The methylol compound is preferably used as a charge transport material.
