Abstract :
[en] Molecules play musical chairs too! Scanning tunneling microscopy reveals how subtle changes in molecular structure can dramatically affect the intermolecular and interfacial forces governing the self-assembly of [5,5']-bisphenyl-[2,2']-bithiophene alkyl derivatives at the graphite-solution interface. Experiments performed in a competitive scenario (see image) show that one derivative can be preferentially physisorbed or even cause the desorption of an already existing monolayer.
