New 2-pyridone-based donor–acceptor dyes: the effect of the donor group position, type of π-linker and acid–base characteristics of the medium on the photophysical properties

“…24 Furthermore, 3-cyanopyridone derivatives have also found applications in DSSCs, 25 OLED devices, 26 and even in the visualization of latent fingerprints on diverse surfaces. 27,28 It should also be noted that pyridones exhibit a tautomeric equilibrium in solution, with the cyanopyrid-2-one fragment demonstrating acidic properties. These properties significantly broaden the potential appli-cation scope of novel compounds of this series.…”

Simple Donor–π–Acceptor Compounds Exhibiting Aggregation-Induced Emission as Hidden Fingerprints Detecting Agents

“…More specifically, a key role in visualization is played by the adhesion forces between the powder and the fingerprint residue (this residue consists of eccrine sweat and sebaceous secretion). In contrast, these adhesive forces are influenced by two factors: pressure deficit and electrostatic attraction [10][11][12][13].…”
