Abstract
The unique properties of pyrenyl-chalcones (pchs) including strong π-delocalized electrons and a tuneable structure, offer significant potential for advanced optical technologies as a promising, cost-effective, and sustainable alternative for high-performance nonlinear optical (nlo) photonics. Herein seventeen novel pchs were synthesized through claisen-schmidt condensation and classified into four groups: halogens (1a-1d), amines (2a-2e), thiophene (3a-3d), and hydrocarbon (4a-4d) chalcones. All compounds were recrystalized via slow evaporation method and only nine compounds form single crystals. Single crystals x-ray diffraction (scxrd) analysis was performed to investigate crystallographic structure. Spectroscopy studies of the compounds were performed using fourier transform infrared (ftir), nuclear magnetic resonance (nmr), and ultraviolet-visible (uv-vis) absorption techniques. Nlo properties were evaluated using the z-scan technique and optical limiting measurements.
