A helical foldamer possessing conformationally switchable metal-binding linkers underwent supramolecular polymerization to form a helical nanofiber. A reversible helix-to-helix transition of the helical nanofiber took place upon cooperative binding and release of Ag(I) ions via a metal-coordination-driven W-to-U-shape conformational change of the linkers in a positive allosteric manner.

compounds, that is, addition of free radicalsgenerated in situ to access various acyl hydrazides, has been developed. The protocol provides a novel strategy for the synthesis of valuable acyl hydrazides. The transformation features mild reaction conditions, good tolerance of functional groups, and a broad substrate scope. In view of the importance of acyl hydrazides in functional materials and medicinal
