Abstract

An electrically conducting organic compound comprising a condensed polycyclic aromatic compound containing from 8 to 14 condensed rings and being solubilized in a solvent by the introduction of a functional group into any condensed ring of the compound. The electrically conducting organic compound is used as a constituent element in the production of electronic devices.

Claims (18)

1. An electronic device comprising, as one member thereof, a constituent element formed from the electrically conducting organic compound, in which said organic compound is an ovalene derivative represented by the following formula (I):

wherein R 1 to R 8 , which may be the same or different, each represents hydrogen atom on an arbitrary substituent, provided that at least two of R 1 to R 8 are a silane group; or

a bianthrene derivative represented by the following formula (II):

wherein R 1 to R 6 , which may be the same or different, each represents a hydrogen atom or an arbitrary substituent, provided that at least two R 1 to R 5 are a silane group.

2. The electronic device as defined in claim 1 , in which said organic compound has a field effect mobility of 0.001 cm 2 /Vs or more.

3. The electronic device as defined in claim 1 , in which said organic compound has a molecular weight of from 100 to 2,000.

4. An electronic device comprising, as one member thereof, a constituent element formed from the electronically conducting organic compound, in which said organic compound is an ovalene derivative represented by the following formula:

5. An electronic device comprising, as one member thereof, a constituent element formed from the electrically conducting organic compound, in which said organic compound is a bianthrene derivative represented by the following formula:

6. An electronic device in an organic thin film transistor comprising a substrate having thereon a gate electrode, a gate insulator, a source electrode, a drain electrode and a channel layer, the channel layer being formed of an electrically conducting organic compound, in which said organic compound is an ovalene derivative represented by the following formula (I):

wherein R 1 to R 6 , which may be the same or different, each represents a hydrogen atom or an arbitrary substituent, provided that at least two of R 1 to R 8 are a silane group; or

a bianthrene derivative represented by the following formula (II);

wherein R 1 to R 6 , which may be the same or different, each represents a hydrogen atom or an arbitrary substituent, provided that at least two of R 1 to R 6 are a silane group.

7. The electronic device as defined in claim 6 , wherein the substrate comprises a plastic material.

8. The electronic device as defined in claim 1 or 6 , wherein the constituent element is formed by dissolving said electrically conducting organic compound in a solvent.

9. The electronic device as defined in claim 8 , wherein the constituent element is formed by coating and curing a solution of said electrically conducting organic compound.

10. The electronic device as defined in claim 8 , wherein the constituent element is formed by printing and curing a solution of the electrically conducting organic compound.

11. The electronic device as defined in claim 1 or 6 , which has flexibility and is foldable.

12. The electronic device as defined in claim 1 or 6 , which is in the form of electronic paper.
