title: Polymorphism and isomerisation of an azobenzene derivative on gold.
abstract: M-TBA (4-methoxy-3,30,5,50-tetra-tert-butylazobenzene) adsorbed on a gold (111) surface was found to form four different polymorphs, two of which isomerizable at -1.7 V, but with a low propensity for further isomerisation of nearby molecules (C. Dri, M. V. Peters, J. Schwarz, S. Hecht, L. Grill, Nat. Nanotechnol., 2008, 3, 649-653). Atomistic simulations investigate the origin of the effects.
