[Problem] To provide an organic compound that is easy to synthesize, and has excellent chemical stability, semiconductor characteristics (high carrier mobility) and high solubility in a solvent. [Solution] A compound represented by formula (1) or formula (2) :
wherein, in formula (1), X is oxygen, sulfur or selenium; n is 0 or 1; R 1 to R 3 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 R 1 to R 3 are simultaneously hydrogen is excluded, and a case where X is sulfur and all of R 1 are simultaneously butyl is also excluded. In formula (2), X is oxygen, sulfur or selenium; n is 0 or 1; R 1 to R 2 are hydrogen, alkyl having 1 to 20 carbons, aryl, pyridyl, furyl, thienyl, thiazolyl or the like; however, a case where all of R 1 to R 2 are simultaneously hydrogen is excluded. |
