Abstract
The Front Cover shows how full-color solvatochromic fluorescence has been achieved by using a push–pull type π-conjugated molecule (placed in the flask) featuring a rigid, planar indenoindene core as the fluorophore. The fluorescence quantum yield exceeds 0.90 in aprotic solvents, and the emission color ranges from blue to red depending on solvent polarity, as represented by the colored smoke in the flask. More information can be found in the Research Article by H. Tsuji and co-workers (DOI: 10.1002/ejoc.202401471).
