Reaction of 1,2‐di(thiophen‐2‐yl)ethane‐1,2‐dione and (1 R ,2 R )‐(−)‐diaminocyclohexane afforded a homochiral quinoxaline derivative (4a R ,8a R )‐2,3‐di(thiophen‐2‐yl)‐decahydroquinoxaline ( 1 ). Fluorescent analysis exhibits an intense blue emission band at 386 nm. Crystallographic analysis showed that it belongs to chiral space group P 2 1 with ferroelectric behavior, and a typical ferroelectric feature of electric hysteresis loop was obtained. The dielectric constant of compound 1 was measured at room temperature.
