Structure and characterization of model complex and polymer. a Possible stereochemical structures for [Zn(Hbimcp)2]2+ complex. b Variable temperature 1H nuclear magnetic resonance (NMR) for Zn(Pr-Hbimcp)Cl2. c Three possible pathways for ligand exchange process. d The structure of polymer complex Zn(Hbimcp)2-PDMS. e Typical force–extension curves during force spectroscopy measurements of the stretching of a single chain of Hbimcp-PDMS (blue line) and of Zn(Hbimcp)2-PDMS (red line). Scale bar for the vertical axis, 50 pN
