Ferrocene-based redox-responsive polymer gels: Synthesis, structures and applications

Ferrocene‐Functionalized Silsesquioxane‐Based Porous Polymer for Efficient Removal of Dyes and Heavy Metal Ions

“…It is clear that the absorbed volume of nitrogen increases dramatically at low relative pressure and slowly at high relative pressure. Moreover, a slight hysteresis can be observed in the desorption isotherm, indicating the presence of micropores and mesopores in Fc‐HPP . The surface area of Fc‐HPP was determined by the specific Brunauer–Emmett–Teller surface area ( S BET ) method.…”

Oxidative regulation of the mechanical strength of a C–S bond

“…Relative to polymeric systems that respond to light, 4 heat, 5 pH, 6 force, 7 and other stimuli, [8][9][10] polymers whose properties are responsive to oxidation state play remarkable roles in controlled assembly, 11 self-healing ability, 12 adjusting gel volume, 13 and drug delivery. [14][15][16] Construction of such polymers is achieved through incorporation of oxidizable or reduceable (including, in some circumstances, those can be reversibly switched between two oxidation states) chemical functional units, including ferrocene, 17 selenide/diselenide, 18,19 platinum complexes, sulde, aryl oxalate esters, phenylboronic esters, thioketals, proline, etc. 15 Among these systems, we were drawn to sulde containing polymers, which are easily constructed through thiol-ene "click" reactions, 20 Michael additions, 21 ring-opening of ethylene/propylene sulde 22,23 and other scalable and accessible chemistry pathways.…”

Stimuli-Responsive Materials for Tissue Engineering and Drug Delivery

“…These are a group of metal-containing polymers with high chemical stability which in principle can be obtained in two ways: incorporating covalently bound ferrocene into the polymer in the main chain (backbone) or by attachment of ferrocenyl units to pendant groups adjacent to the polymer backbone. The main aspects of their synthesis and structure can be found in recent reviews for both types of polymers [169,170]. As we mentioned before, herein we will focus on their application as redox-sensitive biomaterials or nanosystems intended for drug delivery.…”
