Chalcogen-containing organic compound and use thereof

摘要

An organic compound represented by formula (1) or formula (2) that is easy to synthesize, and has excellent chemical stability, semiconductor characteristics (high carrier mobility) and high solubility in a solvent.;;in formula (1), X is oxygen, sulfur or selenium; n is 0 or 1; R1 to R3 are hydrogen, fluorine, alkyl having 1 to 20 carbons, aryl, pyridyl, furyl, thienyl, thiazolyl or the like. However, except for a case where X is selenium, a case where all of R1 to R3 are simultaneously hydrogen is excluded, and a case where X is sulfur and all of R1 are simultaneously butyl is also excluded. In formula (2), X is oxygen, sulfur or selenium; n is 0 or 1; R1 to R2 are hydrogen, alkyl having 1 to 20 carbons, aryl, pyridyl, furyl, thienyl, thiazolyl or the like; however, a case where all of R1 to R2 are simultaneously hydrogen is excluded.
