2 results about "Quinone" patented technology

Provided is a quinone derivative represented by general formula (1). In general formula (1), R1 represents a group selected from the group consisting of an optionally substituted alkyl group having 1-8 carbon atoms, an aryl group that has 6-14 carbon atoms and that may comprise an alkyl group having 1-6 carbon atoms, and a cycloalkyl group having 3-20 carbon atoms. These groups may be substitutedwith one or more halogen atoms. The two R1 may be the same or different from each other. R2 represents a hydrogen atom, an optionally substituted alkyl group having 1-6 carbon atoms, an aryl group having 6-14 carbon atoms, a cycloalkyl group having 3-20 carbon atoms, or an optionally substituted heterocyclic group having 3-14 carbon atoms. The two R2 may be the same or different from each other.

The invention relates to a polymer acceptor material. The polymer acceptor material is characterized by comprising an electron-deficient conjugated unit, and one of a hydrogen atom, a halogen atom, oran alkyl group having 1 to 30 carbon atoms, at least one of the carbon atoms is substituted with a halogen atom, an oxygen atom, an alkenyl group, an alkynyl group, an aryl group, a hydroxyl group, an amino group, a carbonyl group, a carboxyl group, an ester group, a cyano group, or a nitro group. The material is a conjugated polymer containing thienobenzene, the material is a conjugated main chain with a quinone structure, and the absorption spectrum of the material can be effectively broadened. The material has near-infrared absorption and high electron mobility, can be applied to organic photovoltaic devices as an electron acceptor material, and achieves a good device effect.
