Thin films of 2-(3,5-Bistrifluoromethylphenyl)-3-(3-Methoxyphenyl)acrylonitrile (3-MeO- BTFMAN) were prepared with different film thicknesses (8.51 µm, 16.72 µm, and 27.06 µm) using the spin-coating method, with DMSO as the solvent. The photonic properties and refractive indices of the prepared 3-MeO-BTFMAN solution and films were thoroughly investigated using a combination of experimental and theoretical methods. However, as the effect of film thickness on photonic properties could not be explored using Density Functional Theory (DFT) method, this aspect was analyzed solely through experimental approaches. The molecular structure of the 3-MeO-BTFMAN compound was analyzed through a combination of theoretical calculations using the DFT method and experimental analyses involving via X-ray diffraction and spectroscopic techniques. Results showed that the optical band gap of the 3- MeO-BTFMAN film decreased from 3.268 eV to 3.199 eV with increasing film thickness, which demonstrates the impact of film thickness on photonic properties. Additionally, the refractive index of the film exhibited normal dispersion behavior. These findings suggest that the 3-MeO-BTFMAN films hold promise for applications in optoelectronic devices.
