Abstract

Provided are an organic semiconductor material having high charge transfer capability, oxidation stability, and solvent solubility, as well as an organic semiconductor element using this material, a new aromatic heterocyclic compound used in this element, and a method of manufacturing the compound. The aromatic heterocyclic compound is expressed by general formula (1), the compound having two hetero atoms, and having a structure that condenses six rings. In the formula, X represents an oxygen atom or N-R, and R represents a hydrogen atom or a monovalent substitution group.

Description

technical field

[0001] The present invention relates to a novel aromatic heterocyclic compound, an organic semiconductor material containing the same, an organic semiconductor film obtained by using the organic semiconductor material, and an organic semiconductor element such as an organic field effect transistor. Background technique

[0002] In general, a semiconductor element using silicon, an inorganic semiconductor material, requires a high-temperature process and a high-vacuum process to form a thin film. Since a high-temperature process is required, it is impossible to form a thin film of silicon on a plastic substrate or the like, so it is difficult to impart flexibility or reduce weight to a product incorporating a semiconductor element. In addition, since a high-vacuum process is required, it is difficult to increase the size and cost of products incorporating semiconductor elements.

[0003] Therefore, in recent years, organic semiconductor elements using organic...
