Structural characterizations of oligopyridyl foldamers, α-helix mimetics

Protein-protein interactions are central to many biological processes, from intracellular communication to cytoskeleton assembly, and therefore represent an important class of targets for new therapeutics. The most common secondary structure in natural proteins is an α-helix. Small molecules seem to be attractive candidates for stabilizing or disrupting protein-protein interactions based on α-helices. In our study, we assessed the ability of oligopyridyl scaffolds to mimic the α-helical twist. The theoretical as well as experimental studies (X-ray diffraction and NMR) on conformations of bipyridines in the function of substituent and pyridine nitrogen positions were carried out. Furthermore, the experimental techniques showed that the conformations observed in bipyridines are maintained within a longer oligopyridyl scaffold (quaterpyridines). The alignment of the synthesized quaterpyridine with two methyl substituents showed that it is an α-helix foldamer; their methyl groups overlap very well with side chain positions, i and i + 3, of an ideal α-helix.

Molecular design of high-molecular-orientation electron-transport materials and application to organic light-emitting diodes

Two novel electron-transport materials (ETMs), 2,3′-Bpy- TP and 2,4′-Bpy-TP, with high horizontal molecular orientation to substrates, were synthesized. It was shown by measuring the IR absorption spectra of their deposited thin films that C-H N hydrogen bonds are formed between the 2,3′-Bpy-TP molecules and between the 2,4′-Bpy-TP molecules. It was also shown that there is a closed relationship between their molecular orientations and the driving voltages of electron-only devices (EODs) using them as electron-transport layers (ETLs).
