Stimuli-responsive degrafting of polymer brushes via addressable catecholato-metal attachments

Asger Holm Agergaard, Steen Uttrup Pedersen, Henrik Birkedal, Kim Daasbjerg 10.1039/d0py00916d Catecholato-metal complexes are widely used in functional materials such as hydrogels, where the dynamic nature of the coordination bonds between catechol and metal ions contributes to self-healing and stimuli-responsive properties. Herein, we translate the pH-controlled speciation of such complexes known from bulk to a…

Synthesis and Closed-Loop Recycling of Self-Immolative Poly (dithiothreitol)

Andreas Sommerfeldt, Kim Daasbjerg, Steen Uttrup Pedersen, Sunirmal Pal https://doi.org/10.1021/acs.macromol.0c00861 Self-immolative polymers (SIPs) are promising members of the emerging class of recyclable polymers with the ability to end-to-end depolymerize to their monomers. Unfortunately, SIPs are often synthesized by cumbersome procedures at low temperatures in protected atmosphere. In this study, a SIP with a novel poly(disulfide)…
