Electronic microdevices of self-bending coronene crystals are developed to reveal an unexplored link between mechanical deformation and crystal function. First, af acile approach towards length/width/curvature-controllable microcrystals through bottom-up solution crystallization was proposed for high processability and stability.The bending crystal devices show as ignificant increase beyond seven orders of magnitude in conductivity than the straight ones,providing the first example of deformation-induced function enhancement in crystal materials.B esides,d ouble effects caused by bending, including the change of p electron level as well as the enhancement of carrier mobility,were determined, respectively by the X-rayp hotoelectric spectroscopya nd X-ray crystallography to coexist, contributing to the conductivity improvement. Our findings will promote future creation of flexible organic crystal systems with deformation-enhanced functional features towards customized smart devices.

We present a spironolactone–saccharin cocrystal hydrate as the first example of a crystal that jumps without changes in either the lattice parameter or the molecular conformation to highlight the unique advantages of the jumping-mate strategy.
