Crystalline spring : Single crystals formed from caffeine, 4‐chloro‐3‐nitrobenzoic acid, and methanol (1:1:<1) have an interlocked structure with weak interactions in the three perpendicular directions, as well as solvent channels, and display reversible elastic bending. Excellent conservation of long‐range order even after many bending cycles is observed, thus demonstrating the opportunities for flexible organic materials.
