[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.
[问题] 提供一种易于合成、具有优异的化学稳定性、半导体特性(高载流子迁移率)和在 溶剂中的高溶解度的有机化合物。
[解决方案] 一种由式(1)或式(2)表示的化合物:
其中,在式 (1) 中,X 是氧、硫或硒;n 是 0 或 1;R1 至 R3 是氢、氟、具有 1 至 20 个碳原子的烷基、芳基、吡啶基、呋喃基、噻吩基、噻唑基或类似物。但是,除了 X 为硒的情况外,不包括 R1 至 R3 全部同时为氢的情况,也不包括 X 为硫且 R1 全部同时为丁基的情况。在式 (2) 中,X 是氧、硫或硒;n 是 0 或 1;R1 至 R2 是氢、含 1 至 20 个碳原子的烷基、芳基、吡啶基、呋喃基、噻吩基、噻唑基等;但不包括 R1 至 R2 全部同时为氢的情况。
