Stimuli-Responsive Ruthenium-Containing Polymers.

Ruthenium-containing polymers (RCPs) are a type of functional metallopolymer. Stimuli-responsive RCPs in which the responsive behaviors derive from the structure variation of Ru complexes are reviewed in this Feature Article, with particular focus on redox responsive RCPs and photoresponsive RCPs. On the basis of the recent progress, the response principle, syntheses, structures, properties, applications, and remaining challenges of such stimuli-responsive RCPs are discussed.
