Among the various types of photomechanical deformations of organic crystals, photoinduced
elongation of millimeter-scale crystals has yet to be demonstrated. Here we report that the …

The emergence of flexible organic crystals changed the perception of molecular crystals that
were regarded as brittle entities over a long period of time, and sparked a great interest in …

Crystalline materials that exhibit reversible mechanical responses upon exposure to
external stimuli have garnered significant attention owing to their potential applications in …

The approach for enhancing the elasticity of crystals with suboptimal elastic performances
through a rational design was presented. A hydrogen-bonding link was identified as a …

We herein report the tuning of mechanical plasticity of a series of 2-benzylidene-1-indanone
derivative crystals through controlling intermolecular interactions for the first time. The roles …

Organic crystals with flexibility have been a research hotspot due to their huge potential in
flexible optoelectronics. However, most organic crystals are brittle, which greatly restricts …

Flexible crystals with plasticity and elasticity that exhibit phosphorescent emission are quite
rare yet highly significant for their potential applications. In our study, we present an example …

Practical applications of flexible crystals are often limited due to their monotonous
properties. In this study, multi-stimuli-responsive crystals of isonicotinamide (INA), which …

Most crystal engineering strategies exercised until now mainly rely on the alteration of weak
non-covalent interactions to design structures and thus properties. Examples of mechanical …
