Problems solved by technology

However, compared with inorganic semiconductors, electrons and holes in organic semiconductors are strongly bound, so the photoelectric conversion rate is extremely low
Furthermore, a combination of an organic semiconductor and an inorganic semiconductor has also been proposed, but as mentioned above, the conductivity of the organic semiconductor is low, so a high photoelectric effect cannot be obtained.

Abstract

Disclosed is a composition (for example, a coating composition) which can be used to form an organic semiconductor having superior conductivity, solvent resistance, heat resistance and durability. Also disclosed is an organic semiconductor which is formed using the composition. The composition comprises: an aromatic polycarbonyl compound having a carbonyl group as a reactive site; and at least one aromatic reaction component selected from an aromatic polyamine having an amine group as a reactive site, and an aromatic heterocyclic compound having a plurality of unmodified alpha-carbon positions as reactive sites, said a-carbon positions being adjacent to heterocyclic heteroatoms. If the aromatic reaction component is an aromatic heterocyclic compound, the aromatic polycarbonyl compound is an aromatic polyaldehyde compound. An organic semiconductor having a three-dimensional crosslinked structure is formed using a composition in which at least one component among the aromatic polycarbonyl compound and the aromatic reaction component has at least three reactive sites.
