Abstract |
We have developed model light-emitting metallogels functionalized with lanthanide metal-ligand (M-L) coordination complexes via a terpyridyl end-capped 4-Arm-PEG polymer. The optical properties of these highly luminescent polymer networks are readily modulated over a wide spectrum including white light emission by simply tuning lanthanide metal ion stoichiometry. Furthermore, the dynamic nature of the Ln-N coordination bonding leads to a broad variety of reversible stimuli-responsive properties (mechano-, vapo-, thermo- and chemochromism) of both sol-gel systems and solid thin films. The versatile functional performance combined with the ease of assembly suggests that this lanthanide coordination polymer design approach offers a robust pathway for future engineering of multi-stimuli responsive polymer materials. |
