Mechanophoric 3‐Arm Star Functional Block Copolymer Based on Rhodamine Derivative

Macromolecular Materials and Engineering, EarlyView.
Mechanoresponsive rhodamine containing linear and star block and random copolymers were synthesized and characterized. All materials transitioned into a “switch‐on” state in the film form, but only the star block copolymer architecture exhibited a complete and precise peak shift upon stretching, providing new insights into the mechanochemical ...

Light-Driven Expansion of Spiropyran Hydrogels

Journal of the American Chemical Society, 2020
The incorporation of molecular switches in organic structures is of great interest in the chemical design of stimuli-responsive materials that mimic the complex functions of living systems. Merocyanine dyes that convert to spiropyran moieties upon exposure to visible light have been extensively studied as they can be incorporated in hydrated covalent ...

Hydrogels Incorporating Donor–Acceptor Stenhouse Adducts as a Platform for Photoinduced, On‐Off Switchable Release of Small Molecule Cargos

Macromolecular Rapid Communications, EarlyView.
Donor–acceptor Stenhouse aDdducts (DASAs) are known for their photoinduced tautomerization, which, when conjugated to block copolymers, can self‐assemble into tuneable polymersomes. These DASA‐polymersomes are being investigated for light‐controlled cargo release in biomedical applications.

Optical switching of protein interactions on photosensitive–electroactive polymers measured by atomic force microscopy [PDF]

, 2013
The ability to switch the physico-chemical properties of conducting polymers opens up new possibilities for a range of new applications. Appropriately functionalised materials can provide routes to multi-modal switching, for example in response light and/

A merocyanine-based conductive polymer [PDF]

, 2013
We report the first example of a conducting polymer with a merocyanine incorporated into the polymer backbone by electropolymerisation of a spiropyran moiety covalently linked between two alkoxythiophene units.

Switchable and reversible wetting properties

Responsive Materials, EarlyView.
Reversible and switchable wettability is attainable by integrating stimuli‐responsive materials. This review categorizes different external stimuli capable of modulating wettability. Abstract Controlling surface wettability is essential for various applications such as water harvesting, oil/water separation, and smart skin technologies.
