Abstract
Official abstract text for this publication.
To provide a fused hetero 5-membered ring molecule having further sufficiently high hole mobility. Disclosed is a fused hetero 5-membered ring molecule having, in one molecule, eight aromatic rings including three or five hetero 5-membered rings, and the eight aromatic rings having one or two naphthalene structures. The three or five hetero 5-membered rings are each independently selected from the group consisting of a thiophene ring, a selenophene ring, and a furan ring.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fused hetero 5-membered ring molecule comprising eight aromatic rings in one molecule, the eight aromatic rings including three hetero 5-membered rings, and the eight aromatic rings having one naphthalene structures, wherein the fused hetero 5-membered ring molecule is represented by a general formula (I): wherein Ra 1 to Ra 14 are each independently a hydrogen atom; and M 1 to M 3 are each independently a sulfur atom. 2. A p-type semiconductor film comprising the fused hetero 5-membered ring molecule according to claim 1 . 3. An electronic device comprising the p-type semiconductor film according to claim 2 . 4. An electronic device comprising a transistor, the transistor including a source electrode, a drain electrode, a gate electrode, and a semiconductor film, wherein the semiconductor film is the p-type semiconductor film according to claim 2 .
