Liquid crystals have been intensively studied as functional materials. Recently, integration of
various disciplines has led to new directions in the design of functional liquid‐crystalline …

The development of polymeric materials with switchable properties upon exposure to
external stimuli such as light, heat, force, acids/bases, and chemicals has attracted much …

Real-time monitoring of strain/stress in polymers is a big challenge to date. Herein, we for
the first time report an ESIPT (excited-state intramolecular proton transfer)-based …

With the serendipitous discovery of crown ethers by Pedersen more than half a century ago
and the subsequent introduction of host–guest chemistry and supramolecular chemistry by …

Polymer gels have recently attracted attention for their application in flexible devices, where
mechanically robust gels are required. While there are many strategies to produce tough …

Mechanochromic mechanophores permit the design of polymers that indicate mechanical
events through optical signals. Here we report rotaxane-based supramolecular …

Mechanochromophores based on conformational changes of donor–acceptor–donor (DAD)
springs allow sensing of forces acting on polymer chains by monotonic changes of …

A supramolecular mechanophore that can be integrated into polymers and indicates
deformation by a fluorescence color change is reported. Two perylene diimides (PDIs) were …

Mechanochromic mechanophores are reporter molecules that indicate mechanical events
through changes of their photophysical properties. Supramolecular mechanophores in …

Cephalopods can display variable body color/patterns upon environmental stimulation via
bioelectricity‐controlled muscle contraction/expansion of skin chromatophores. However, it …
