Scanning tunneling microscopy: a unique tool in the study of chirality, dynamics, and reactivity in physisorbed organic monolayers.
S. De Feyter,Andre J. Gesquiere,Mohamed M. S. Abdel-Mottaleb,P. C. M. Grim,F. C. De Schryver,C. Meiners,M. Sieffert,Suresh Valiyaveettil,Klaus Müllen +8 more
TL;DR: Making use of a fast scanning mode, dynamic processes in these adlayers have been visualized and the effect of molecular chirality on the monolayer formation and provided a unique way to study chemical reactions at the liquid-graphite interface.

Steven De Feyter,P. C. M. Grim,Markus Rücker,P. Vanoppen,C. Meiners,M. Sieffert,Suresh Valiyaveettil,Klaus Müllen,Frans C. De Schryver +8 more
TL;DR: The supramolecular packing mode of physisorbed monolayers built up by chiral isophthalic acid derivatives and coadsorbed achiral solvent molecules was imaged at the liquid/graphite interface with scanning tunneling microscopy (STM).

Dynamics in physisorbed monolayers of 5-alkoxy-isophthalic acid derivatives at the liquid/solid interface investigated by scanning tunneling microscopy
Andre J. Gesquiere,Mohamed M. S. Abdel-Mottaleb,Steven De Feyter,Frans C. De Schryver,M. Sieffert,Klaus Müllen,A. Calderone,Roberto Lazzaroni,Jean-Luc Brédas +8 more
TL;DR: It is observed that non-fluorinated molecules progressively substitute the fluorinated molecules in monolayer dynamics, illustrating the metastable equilibrium that exists at the liquid/solid interface, between the physisorbed molecules and the supernatant solution.

S. De Feyter,Andre J. Gesquiere,P. C. M. Grim,F. C. De Schryver,Suresh Valiyaveettil,C. Meiners,M. Sieffert,Klaus Müllen +7 more
TL;DR: In this article, the enantiomers of a chiral terephthalic acid derivative, 2,5-bis[[10-(2-methylbutoxy)decyl]oxy]terephthalmic acid, have been characterized on graphite (HOPG) at the same time.

Photodimerization of Cinnamate Derivatives Studied by STM
M. M. S. Abdel-Mottaleb,S. De Feyter,A. Gesquiere,M. Sieffert,Markus Klapper,Klaus Müllen,F. C. De Schryver +6 more
TL;DR: In this article, the photochemical dimerization of two cinnamate derivatives, C18CinnC18 and C18cinnC10, has been investigated at the liquid/graphite interface by scanning tunneling microscopy (STM).
