A new variety of non-symmetrical triphenylene-based discogens has been synthesized by intramolecular Scholl cyclodehydrogenation reaction of kinked terphenylenes using the FeCl3/MeNO2 couple as an efficient oxidant. The “Janus-like” tetrakis(alkoxy)triphenylene discogens containing electron-withdrawing groups, such as cyano-, chloro- and fluoro-substituents, or electron-donating moieties, such as...
Twelve triphenylene discogens with unsaturated periphery (abbreviated as C18H6(OC5H11)6−x(OR)x (x = 1, 2, 3), R = -C3H6CH == CH2 (a), -C3H6C C ≡CH (b), -C2H4OCH== CH2 (c)) were synthesized and characterized. The thermotropic liquid crystal properties were studied by using polarized optical microscopy, differential scanning calorimetry and X-ray diffractometry. The results showed that all triphenylenes...
