“…On the other hand, chalcones are a class of organic compounds that contain a central α,β-unsaturated carbonyl system, which has attracted significant attention, due to their diverse applications in the fields of medicine, material science, and optics . Moreover, the chalcones due to the π-conjugated system and the two aromatic rings that act as donors and acceptors provide a reasonable fluorescence quantum yield, efficient stabilization of charge-transfer processes in the excited state, long-wavelength emission (λ em ), and large Stokes shifts, which means that they have potential applications in fluorescence microscopy or bioimaging applications as they can improve image sensitivity by reducing the interference caused by self-absorption or autofluorescence. − …”

In this article, three unsymmetrical 7-(diethylamino)quinolone chalcones with D-π–A-D and D-π–A-π-D type push–pull molecular arrangements were synthesized via a Claisen–Schmidt reaction. Using 7-(diethylamino)quinolone and vanillin as electron donor (D) moieties, these were linked together through the α,β-unsaturated carbonyl system acting as a linker and an electron acceptor (A). The photophysical properties were studied, revealing significant Stokes shifts and strong solvatofluorochromism caused by the ICT and TICT behavior produced by the push–pull effect. Moreover, quenching caused by the population of the TICT state in THF–H2O mixtures was observed, and the emission in the solid state evidenced a red shift compared to the emission in solution. These findings were corroborated by density functional theory (DFT) calculations employing the wb97xd/6-311G(d,p) method. The cytotoxic activity of the synthesized compounds was assessed on BHK-21, PC3, and LNCaP cell lines, revealing moderate activity across all compounds. Notably, compound 5b exhibited the highest activity against LNCaP cells, with an LC50 value of 10.89 μM. Furthermore, the compounds were evaluated for their potential as imaging agents in living prostate cells. The results demonstrated their favorable cell permeability and strong emission at 488 nm, positioning them as promising candidates for cancer cell imaging applications.
