Molecular reorientation: Copper (II) phthalocyanines are investigated on the rutile TiO 2 (011)‐(2×1) surface. At first, a quasi‐ordered wetting monolayer is formed, after which well‐ordered islands composed of flat‐lying molecules appear (picture, left). Post‐deposition thermal annealing at 200 °C leads to a complete reorientation of the second layer so that the molecules adopt an upright configuration (picture, right).
