Abstract

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

1 . A fused hetero 5-membered ring molecule comprising eight aromatic rings in one molecule, the eight aromatic rings including three or five hetero 5-membered rings, and the eight aromatic rings having one or two naphthalene structures,
wherein 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.

2 . The fused hetero 5-membered ring molecule according to claim 1 , wherein the three or five hetero 5-membered rings are all hetero 5-membered rings having the same hetero atom.

3 . The fused hetero 5-membered ring molecule according to claim 1 , wherein the fused hetero 5-membered ring molecule is represented by a general formula (I), (II), (III) or (IV):

in the general formula (I), Ra 1 to Ra 14 are each independently a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, or an aryl group having 6 to 18 carbon atoms; M 1 to M 3 are each independently a sulfur atom, a selenium atom, or an oxygen atom;

in the general formula (II), Rb 1 to Rb 14 are each independently a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, or an aryl group having 6 to 18 carbon atoms; M 1 to M 3 are each independently a sulfur atom, a selenium atom, or an oxygen atom;

in the general formula (III), Rc 1 to Rc 14 are each independently a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, or an aryl group having 6 to 18 carbon atoms; M 1 to M 3 are each independently a sulfur atom, a selenium atom, or an oxygen atom;

in the general formula (IV), Rd 1 to Rd 10 are each independently a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, or an aryl group having 6 to 18 carbon atoms; M 1 to M 5 are each independently a sulfur atom, a selenium atom, or an oxygen atom.

4 . The fused hetero 5-membered ring molecule according to claim 1 , wherein
the eight aromatic rings are condensed with each other to form an aromatic ring portion, and the aromatic ring portion has a linear structure.

5 . The fused hetero 5-membered ring molecule according to claim 4 , wherein in the aromatic ring portion two aromatic rings at an end of the linear structure among the eight aromatic rings are both benzene rings or both hetero 5-membered rings.

6 . The fused hetero 5-membered ring molecule according to claim 4 , wherein
in the aromatic ring portion two aromatic rings at an end of the linear structure among the eight aromatic rings are benzene rings, and the aromatic ring portion has a straight line structure.

7 . The fused hetero 5-membered ring molecule according to claim 4 , wherein
in the aromatic ring portion two aromatic rings at an end of the linear structure among the eight aromatic rings are hetero 5-membered rings, and the aromatic ring portion has a flex line structure.

8 . The fused hetero 5-membered ring molecule according to claim 4 , wherein all aromatic rings adjacent to one of the hetero 5-membered rings are benzene rings.

9 . A p-type semiconductor film comprising the fused hetero 5-membered ring molecule according to claim 1 .

10 . An electronic device comprising the p-type semiconductor film according to claim 9 .

11 . 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 9 .
