“…Recently, the sterically congested hexa(heteroaryl)benzene (HHAB) 4 was formed as two isolable isomers which differ only in the rotation of one methyl-pyridine group. 22 In general, propeller-shaped hexaarylbenzenes (HABs) such as hexa(β-naphthyl)benzene 5 23 have numerous applications in materials sciences as they play roles as liquid crystals, 24 microporous organic solids, 25 molecular capsules, 26 supramolecular electronic materials, 27 molecular rotors, 28 nonlinear optical materials, 29 metal sensors, 30 redox materials, 31 and molecular wires. 32 We report here on quinolinium-substituted benzenes which combine the features of HHABs and polycations as they have to adopt propeller-shaped…”
