Özet
The structural, electronic, and optical properties of the D-π-A chromophore 3-(4-methoxyphenyl)-2-(3-(trifluoromethyl)phenyl)acrylonitrile (MTFMAN) were comprehensively investigated using a multiscale approach combining single crystal X-ray diffraction, UV–Vis spectroscopy, and Density Functional Theory (DFT), including Time-Dependent DFT (TD-DFT) and explicit solvent cluster modeling. X-ray analysis confirmed that the compound crystallizes in a monoclinic system (space group P21/n) with a unit cell volume of 1520.4(4) Å3, stabilized by dominant non-covalent interactions, specifically π···π stacking and C–H···F interactions. Optical measurements demonstrated significant solvatochromism; as solvent polarity increased from acetone to DMSO, the absorption maximum shifted from 339 to 344 nm, and the experimental optical band gap decreased from 3.116 to 3.062 eV. TD-DFT calculations confirmed that the …
