Synergistic Double-Layer Mechanochromic Polymers for Enhanced Strain Sensing and Emission Control

Front Cover: A double-layer polymer system shows mechanochromic fluorescence enhancement under strain. The synergy between a pyrene-based emissive layer and a perylene pigment optical filter enables strain sensing via light emission modulation. More details can be found in article 2500060 by Andrea Pucci, Marco Carlotti, and co-workers.
