Responsive Polyelectrolyte Brushes in Applications: Functions, Stimuli, and Design Considerations

open access: yesAdvanced Materials, EarlyView.
With advances in the synthesis of polyelectrolyte brushes, these coatings of surface‐grafted chains find uses in an increasing number of applications. This review summarizes three core aspects of these brushes: how they introduce functionality to surfaces; how external stimuli influence their properties; and what practical considerations should be ...

Force‐Induced Selective Carbon‐Carbon Bond Cleavage in Mechanoresponsive Topochemical Polymers

open access: yesAdvanced Materials, EarlyView.
A new class of mechanoresponsive polymers based on polybiidenedionediyl (PBIT) derivatives exhibits distinct color changes upon mechanical stimuli such as grinding, milling, and compression. The response arises from depolymerization and backbone conjugation changes.
