Abstract

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 cm2 V−1 s−1 is achieved for spin cast OFETs.
