supramolecular structures. The linear optical absorption coefficient (α) of F3BC and F3NC were analyzed by UV–Vis–NIR spectral analysis and the optical band gaps (Eg) were estimated. TG-DTA analysis revealed that the F3NC crystal has higher thermal stability than F3BC crystal. The third-order nonlinear optical properties of these crystals were studied in solution using Z-scan technique with a continuous wave (CW)
