[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; 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. |

1. A compound represented by formula (1):wherein, in formula (1),
X is oxygen, sulfur or selenium; both of n are each independently 0 or 1; R1 to R3 are each independently hydrogen, fluorine, alkyl having 1 to 20 carbons, aryl, pyridyl, furyl, thienyl or thiazolyl, at least one of hydrogen in the alkyl may be replaced by fluorine, and at least one of hydrogen on a ring of the aryl, the pyridyl, the furyl, the thienyl and the thiazolyl may be replaced by at least one kind selected from halogen and alkyl having 1 to 10 carbons; 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. |
