In crystals, tetraalkyl vanadyl phthalocyanines (OVPc‐Cn) and tetraalkyl titanyl phthalocyanines ( OTiPc‐Cn ) with ABAB symmetry adopt a 2D slipped π–π stacking motif with alkyl chains locating in the space between semiconducting layers formed by Pc cores. Hole mobility approaching 1 cm 2 V −1 s −1 is achieved for spin cast OFETs.
