title: Contraction/extension molecular motion by protonation/deprotonation induced structural switching of pyridine derived oligoamides.
abstract: NMR, mass spectrometry and X-ray diffraction studies show reversible structural interconversion between helical and extended forms of pyridine derived oligoamide molecular strands, by simple protonation/deprotonation.
