Macroscopic single crystals of 4‐hydroxy‐cyanobenzene (4HCB) grown from solution exhibit reproducible and marked 3D mobility anisotropy. Air‐gap OFET measurements along the planar axes a and b deliver average mobilities of 3 × 10 −2 and 6 × 10 −3 cm 2 V −1 s −1 , respectively. Space‐charge‐limited current (SCLC) experiments reveal an average mobility along the c axis of 4 × 10 −6 cm 2 V −1 s −1 .
