Abstract

Four structural isomers of non-peripheral tetrahexyl-substituted vanadyl phthalocy­anine can be easily separated using common laboratory column chromatography on a gram scale. The most abundant isomer, 1,8,18,22-tetrahexyl vanadyl phthalocyanine (I-3), adopts intermolecular 2D cofacial ππ stacking and exhibits a field-effect mobility of up to 0.13 cm2 V−1 s−1.
