We have synthesized the coordination polymers based on Ag(I) ion complexed with pyridine ligands with a bent conformation, and investigated their dynamic self-assembling behavior in aqueous solution. The unique feature of the coordination polymers investigated here is their ability to adopt a helical structure that displays reversible extension-contraction motions, triggered by temperature. It is also notable that this dynamic conformational change leads to a fluorescence switching between the fluorescent stretched and non-fluorescent compressed states of the supramolecular springs. Such mechanical motions of the supramolecular spring may offer intriguing potentials for dynamic nanodevices, optical modulators, and fluorescent thermometers. |
