Benzoselenadiazole‐Functionalized H‐Bonded Arylamide Foldamers: Solvent‐Responsive Properties and Helix Self‐Assembly Directed by Chalcogen Bonding in Solid State
In this study, a series of H-bonded arylamide foldamers bearing benzoselenadiazole ends with solvent-responsive properties have been synthesized. In dichloromethane or dimethyl sulfoxide solvents, the molecules exhibit meniscus or linear structures, respectively, which can be attributed to the unique intramolecular hydrogen bonding behavior evidenced by 1D
