Transformation of energy into motion (work) is one of the basic processes of energy conversion
in nature. The processes of actuation underlying the transduction of light, thermal, or …

An anthracene derivative, 9,10‐dicyanoanthracene, crystallizes as fluorescent needle‐like
single crystals that can be readily plastically bent in two directions. Spatially resolved …

Hygroinduced motion is a fundamental process of energy conversion that is essential for
applications that require contactless actuation in response to the day–night rhythm of …

The anticipated shift in the focal point of interest of solid-state chemists, crystal engineers,
and crystallographers from structure to properties to function parallels the need to apply our …

In the last century, molecular crystals functioned predominantly as a means for determining
the molecular structures via X-ray diffraction, albeit as the century came to a close the …

Critical biological electron-transfer processes involving high-valent oxometal chemistry
occur widely, for example in haem proteins [oxoiron(IV); Fe IV (O)] and in photosystem II. …

Mechanically reconfigurable molecular crystals—ordered materials that can adapt to variable
operating and environmental conditions by deformation, whereby they attain motility or …

During the process of evolution, animals and plants have naturally acquired two capabilities
that are of critical importance for their survival: to evolve and to disperse. Natural motility is a …

The exceptional mechanical flexibility observed with certain organic crystals defies the
common perception of single crystals as brittle objects. Here, we describe the morphostructural …

The extremely rare examples of dynamic single crystals where excitation by light or heat
induces macroscopic motility present not only a visually appealing demonstration of the utility of …
