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 π – π stacking and exhibits a field‐effect mobility of up to 0.13 cm 2 V −1 s −1 .
