Stimuli‐Responsive Ruthenium‐Containing Polymers

Abstract

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.

Dynamic Supramolecular Ruthenium‐Based Gels Responsive to Visible/NIR Light and Heat

“…Such materials have been investigated in a wide field of applications, for example the transduction of mechanical force into chemical reactions, as well as in dynamic self‐healing and optically healable materials . Also a number of ruthenium‐containing metallopolymers have been reported, with a particular focus on their use as stimuli‐responsive polymers . Meanwhile, photocleavable polymers, that is polymers which cleave or degrade in response to irradiation with certain wavelengths of light have been recently developed .…”

“…These so called "dynamers" are designed to undergo reorganization by reversible chemical reactions under the influence of external factors. [7] Meanwhile, photocleavable polymers,t hat is polymers whichc leave or degrade in response to irradiation with certain wavelengths of light have been recently developed. [2] Metallopolymers can offer unique properties and an umber of supramolecular systemsh ave been developed based on dynamic ligand-metali nteractions.…”

Fabrication of a Dual‐Stimuli‐Responsive Supramolecular Micelle from a Pillar[5]arene‐Based Supramolecular Diblock Copolymer for Photodynamic Therapy

“…As a versatile therapeutic cancer treatment with high spatiotemporal precision, PDT has received more attention in recent years . PDT involves the administration of tumor‐localizing photosensitizers (PSs) followed by activation with a specific wavelength of light to generate reactive oxygen species (ROS), which can noninvasively treat diseased tissues .…”
