Up or down? Making use of self‐assembly, the graphite surface is decorated with upright oriented photochromic units organized by a terfluorene platform. The azobenzenes within the monolayer could be converted from the trans to the cis form leading to substantial and reversible structural reorganization, as revealed by scanning tunneling microscopy (STM) studies.
