Cover Feature: A Simply Synthesized Shaking‐induced Small Molecule System with Repeatable and Instantaneous Discoloration Response (Chem. Eur. J. 47/2024)

The instantaneous and repeatable force-related discoloration response (from yellowish to dark green) of a simply synthesized small-molecule solution system is attributed to the accelerated generation of an ortho-OH phenoxyl radical under shaking. More information can be found in the Research Article by J. Wang, J. Liu and co-workers (DOI: 10.1002/chem.202401762).
