• pyrindane – (E)-7-arylmethylene-2-chloro-6,7-dihydro-5H-cyclopenta[b]pyridine-3,4-dicarbonitriles – was developed. Tunable full-color emission was achieved for the synthesized push–pull molecules, solely by changing donor groups while keeping both the conjugated system and acceptor part of the molecule

• acid both in solution and in the solid state. Keywords: dual-state emission; full-color emission; nitriles; push–pull molecules; pyrindane; stilbazole; Introduction Over the past decades, heteroaromatic push–pull molecules have attracted great attention due to their widespread use in materials

• , and optical power limiting applications [33]. Materials with tunable full-color emission based on small organic molecules have attracted attention due to their great potential for applications [34][35][36][37][38][39][40][41][42][43][44]. These compounds provide unique benefits due to their
