The introduction of a seven-membered ring in these push-pull systems can efficiently modulate the optical properties leading to an enhancement of the fluorescence quantum yields up to 0.93 with color tunable emission covering the visible-NIR spectrum.Chemical EngineeringArticleSCOPUS10.1039/d2cc03461a2-s2.0-851352189021364548X35894790
