HIGH MOLECULAR SEMICONDUCTOR LOMPOUNDS HAVING LIGUID CRYSTALLINE PROPERTIES AND ORGANIC TUIN FILM TRANSISTOR UTILIZING SAME

摘要

The present invention relates to a liquid crystal polymer organic semiconductor compound, and a compound represented by the following general formula (1) containing an aromatic and an aliphatic chain in the main chain in the organic thin film transistor using the organic semiconductor layer.; Formula 1 ; Wherein; Ar ₁ and Ar ₂ are each independently A represents wherein, l, m, o, p, q, r is an integer from 0 to 10 or less, respectively;; _{Ar 3, Ar 4, Ar 5} , Ar 6, Ar 7 and Ar ₈ are:; Each independently represent a substituent or substituents selected from the group. Wherein _{Ar 3, Ar 4, Ar 5} , Ar 6, Ar 7 , and R ₂ ~R ₁₉ in the compounds of the Ar ₈ are each independently hydrogen, alkoxy having 1 to 25 alkyl group, having 1 to 25 atoms, or carbon atoms, 1 to 25 alkyl group and / or in which the alkoxy group may be selected from the aryl group a group consisting of a substituted C 6 -C _{30, Ar 9, Ar 10,} Ar 11, and Ar ₁₂ each independently represent an aryl containing 6 to 30 carbon atoms group selected from carbon atoms, from 0 to 30, the heterocyclic aromatic compounds of less than fluoride, an aryl group having 6 or less carbon atoms to 30, an aryl group and a fluorinated aryl group the group consisting of C 1 -C 25 alkyl group and / or C6 to C30 alkoxy group is substituted for may be, and, R ₁ has a carbon number of 1 to 25 polyethylene oxide groups, having 1 to 25 polyalkylene oxide group, a fluorinated alkyl having a carbon number of 1 to 25 alkyl group, a C 1 -C 25 group, having 1 to 25 of Alkoxy group is selected from the group consisting of polydimethyl siloxane group having a carbon number of 1 to 25, n is an integer of not more than 100,000.; The organic semiconductor compound according to the invention is that it is possible to reduce the manufacturing costs in the production of an organic thin film transistor can be formed with ease thin film by a solution process because of the high solubility, due to the superior liquid crystalline facilitate intermolecular arrangement excellent crystallinity to have, and the organic thin film transistor prepared by applying these compounds is a number that, as well as to facilitate the movement of the intramolecular or intermolecular charge by the introduction of a variety of substituents and substituent group, excellent crystallinity and a strong pi-stacking because of the hole and electron mobility is improved, as well as has an excellent off ratio.
