    Abstract Water-soluble peptidomimetics, including peptoids, are promising functional surrogates for biologically relevant, amphiphilic, helical peptides. Twenty amphiphilic peptoid hexamers with predicted helical structures were designed, prepared, and studied using circular dichroism (CD) spectroscopy. The site-specific contributions of aromatic and charged residues to the helical structure of peptoid hexamers in aqueous solution was evaluated, revealing that aromatic residue positioning most significantly impacts structure.

    Abstract Monodisperse, sequence‐specific oligomers that adopt regular three‐dimensional structures, termed foldamers, have found widespread use as biomimetics, sensors, and novel materials. This review highlights recent examples in which steady state and time‐resolved fluorescence techniques have clarified foldamer structure or enabled the development of foldamers with exciting and sophisticated functions. Applications of foldamers include their development into bioactive compounds, supramolecular hosts or sensors, and materials with useful optical properties. Examples that illustrate the use of natively fluorescent and fluorophore‐modified foldamers are discussed along with studies of fluorophore interactions with varied dyes.
