Title:
ORGANIC SEMICONDUCTOR INK, ORGANIC FILM, PHOTOELECTRIC CONVERSION LAYER, METHOD FOR PRODUCING PHOTOELECTRIC CONVERSION LAYER, AND ORGANIC PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/157864
Kind Code:
A1
Abstract:
The present invention provides an organic semiconductor ink which contains a p-type organic semiconductor, an n-type organic semiconductor, a compatibilizer and a solvent, and which is characterized in that: the compatibilizer has a fused ring A of 2 to 5 aromatic hydrocarbon rings as the main skeleton, the fused ring A having two or more substituents R that are adjacent to each other; at least one of the substituents R is a monovalent group of a monocyclic aromatic hydrocarbon ring or an aromatic hydrocarbon ring B that is a fused ring of 2 to 4 aromatic hydrocarbon rings, the aromatic hydrocarbon ring B having the same number of or fewer fused rings in comparison to the fused ring A; and the fused ring A and the aromatic hydrocarbon ring B are not present on the same plane.
