摘要：
Breaking point: The unbinding behavior of single supramolecular polymers formed through quadruple hydrogen bonds between 2-ureido-4(1H)-pyrimidinone (UPy) units was studied by AFM-based single-molecule force spectroscopy. The interactions between individual UPy moieties and the stretching of polyethylene glycol (PEG) spacers in reversible supramolecular polymer chains were unveiled by AFM force-displacement measurements.
