Hierarchically Structured Stimuli-Responsive Liquid Crystalline Terpolymer–Rhodamine Dye Conjugates [PDF]

Molecules
Optically responsive materials are applied in sensing, actuators, and optical devices. One such class of material is dye-doped liquid crystal polymers that self-assemble into cholesteric mesophases that reflect visible light. We report here the synthesis

Full‐Spectrum Mechanochromic Photonic Films with Large Interparticle Distance [PDF]

Advanced Science
Non‐close‐packed crystalline arrays of colloidal particles in an elastic matrix exhibit mechanochromism. However, small interparticle distances often limit the range of reversible color shifts and reduce reflectivity during a blueshift. A straightforward,

A Mechanochromic Hydrogen‐Bonded Rotaxane [PDF]

Macromolecular Rapid Communications, 2020
AbstractTensile forces influence a variety of important biological processes and force sensors are required to study these processes in vivo. Current force sensors are often tailor‐made for a specific application, or activate at much higher forces than those observed at the cellular or tissue level. A versatile force sensor, with tunable mechanical and
