Abstract
An organic thin film transistor includes: an organic thin film which includes a compound represented by the following general formula [A]: X—[—N Ar1Ar2]n [A] where each of Ar1 and Ar2 is selected independently from unsubstituted or substituted aromatic hydrocarbon groups having 6 to 20 carbon atoms and from unsubstituted or substituted aromatic heterocyclic groups having 6 to 20 carbon atoms; and X is selected from unsubstituted or substituted condensed aromatic hydrocarbon groups having 6 to 34 carbon atoms, and the condensed aromatic hydrocarbon groups are monovalent, divalent, trivalent or tetravalent groups; and n is the natural number in the range of 1-4.
Claims21
An organic thin film transistor including:
- an organic thin film;
- first and second electrodes being in contact with said organic thin film, and said first and second electrodes being separated from each other;
- and
- a third electrode being separated from said first and second electrodes, and said third electrode receiving an application of a control voltage which controls a current flowing from one of said first and second electrodes to the other,
- wherein said organic thin film includes at least a compound represented by the following general formula [A]:
- X—[—N Ar1Ar2]n [A]
- where each of Ar1 and Ar2 is selected independently from unsubstituted or substituted aromatic hydrocarbon groups having 6 to 20 carbon atoms and from unsubstituted or substituted aromatic heterocyclic groups having 6 to 20 carbon atoms;
- and X is selected from unsubstituted or substituted condensed aromatic hydrocarbon groups and having 6 to 34 carbon atoms, and said condensed aromatic hydrocarbon groups are monovalent, divalent, trivalent or tetravalent groups;
- and n is the natural number in the range of 1-4.
