• increase the yield of lifted-off molecules during CLL and to produce more intact, supported monolayers [2]. Replacing thiol moieties with groups that bind more strongly to Au [4][64][65], such as selenolates, will also be investigated. Thus, a rich variety of tunable variables, including stamp geometry

• Institute of Technology (KIT), 76021 Karlsruhe, Germany 10.3762/bjnano.8.91 Abstract To study the implications of highly space-demanding organic moieties on the properties of self-assembled monolayers (SAMs), triptycyl thiolates and selenolates with and without methylene spacers on Au(111) surfaces were

Keywords: organic thin films; selenolates; self-assembled monolayers; thiolates; triptycene; Introduction For more than three decades now, self-assembled monolayers (SAMs) have enjoyed ever-increasing popularity in the modification and functionalization of surfaces. Numerous applications of SAMs have been

• only permits relatively low packing densities of thiolates or selenolates, making SAMs of such molecules energetically unfavorable. Consequently, less bulky thiolates/selenolates are able to replace adamantyl-terminated SAMs on gold [18][19]. Thus, the preparation of thiolate and selenolate monolayers
