Organic thin film transistor

An organic thin-film transistor (TFT) comprising:

• an organic film;
• first and second electrodes which are oppositely disposed on upper and lower surfaces of the organic film;
• and
• a third electrode disposed at a specified distance from each of the first and second electrodes, the third electrode being applied with a voltage to control current flowing from one of the first and the second electrodes to the other through the organic film,
• wherein the organic film includes, in the form of a mixture or a single substance, a compound represented by one of general formulae [1] to [6], and
• wherein each of R1 to R80 independently represents a hydrogen atom, halogen atom, hydroxyl group, substituted or non-substituted amino group, nitro group, cyano group, substituted or non-substituted alkyl group, substituted or non-substituted alkenyl group, substituted or non-substituted cycloalkyl group, substituted or non-substituted alkoxy group, substituted or non-substituted aromatic hydrocarbon group, substituted or non-substituted aromatic heterocyclic group, substituted or non-substituted aralkyl group, substituted or non-substituted aryloxy group or substituted or non-substituted alkoxycarbonyl group or carboxyl group;
• any two adjacent groups of R1 to R80 may form a ring;
• “L1” represents substituted or non-substituted alkyl group, substituted or non-substituted alkenyl group, substituted or non-substituted cycloalkyl group, substituted or non-substituted aromatic hydrocarbon group, substituted or non-substituted aromatic heterocyclic group or substituted or non-substituted aralkyl group;
• “Ar1” to “Ar3” represent substituted or non-substituted aromatic hydrocarbon group having carbons from 6 to 20;
• “n” represents an integer from 1 to 3;
• “m” represents an integer from 0 to 2;
• “l” is 0 or 1;
• “s” is 1 or 2;
• “t” represents an integer from 0 to 3;
• and “M” represents a metal ion having a valency of “n+m” or “s+1”.
