“…[21][22][23][24] The emergence of electrospray ionization (ESI), a so ionization technique that enables transferring of intact ions from solution into a mass spectrometer, has facilitated the deposition of a broad range of ions for the analysis of their structures and reactivities on substrates. [25][26][27][28][29][30][31][32] For example, scanning tunneling microscopy of cis-bis(isothiocyanato)bis(2,2 0bipyridyl-4,4 0 -dicarboxylato)-ruthenium(II) on a Au(III) surface revealed that its gas-phase geometry is distorted on the surface to maximize ligand-surface interactions. 33 In another study, so landed vanadium-benzene sandwich clusters were shown to orient on a CH 3 -terminated self-assembled monolayer on gold (HSAM) to maximize interactions between the aromatic rings of the cluster and methylene groups of the HSAM.…”

Helically folded oligoamides of 8-amino-2-quinolinecarboxylic acid composed of up to 41 units were prepared using optimized manual solid-phase synthesis (SPS). The high yield and purity of the final products places these SPS protocols among the most efficient known to date. Furthermore, analytical methods allowing for the clear identification and purity assessment of the products were validated, including 1 H NMR, a seldom used method for such large molecules. Adaption of the SPS protocols, in particular using in situ acid chloride activation under Appel's conditions, made it possible to efficiently implement SPS on a commercial peptide synthesizer, leading to a dramatic reduction of the laboratory work required to produce long sequences. Automation constitutes a breakthrough for the development of helical aromatic oligoamide foldamers.

Supramolecular materials provide a pathway for achieving precise, highly ordered structures while exhibiting remarkable response to external stimuli, a characteristic not commonly found in covalently bonded materials. The design of self‐assembled materials, where properties could be predicted/design from chemical nature of the individual building blocks, hinges upon our ability to relate macroscopic properties to individual building blocks – a feat which has thus far remained elusive. Here, a design approach is demonstrated to chemically engineer the thermal expansion coefficient of 2D supramolecular networks by over an order of magnitude (\boldmath 120 to \boldmath 1000 × 10−6 K−1). This systematic study provides a clear pathway on how to carefully design the thermal expansion coefficient of a 2D molecular assembly. Specifically, a linear relation has been identified between the length of decorating alkyl chains and the thermal expansion coefficient. Counter‐intuitively, the shorter the chains the larger is the thermal expansion coefficient. This precise control over thermo‐mechanical properties marks a significant leap forward in the de‐novo design of advanced 2D materials. The possibility to chemically engineer their thermo‐mechanical properties holds promise for innovations in sensors, actuators, and responsive materials across diverse fields.

Structural adaptations of electrosprayed aromatic oligoamide foldamers on Ag(111)

Abstract: Aromatic foldamers are promising for applications such as molecular recognition and molecular machinery. For many of these, defect free, 2D-crystaline monolayers are needed. To this end, submonolayers were prepared in...
