Abstract
This study utilizes spectral analysis techniques and various computational methods to examine the impact of hydrogen bonding on the optical characteristics of supramolecular liquid crystals within the UV-visible spectrum.This investigation involves the computational method of spectral denoising for quantitative analysis of UV-visible spectra, and then spectral analysis is carried out for the measurement of the optical properties of supramolecular liquid crystals. Other computational methods, like the texture absorbance method, are also employed for colorimetric studies of compounds.The investigation will focus on supramolecular systems:p,n- alkoxy benzoic acid: Do-decyl hydroxybenzoate (nOBA:12HB), where n = 7, 8, and 9. The supramolecular system is formed via hydrogen bond development between the OH acceptor of the non-liquid crystalline substance Do-decyl hydroxyl benzoate (12HB) and the COOH donor of the liquid crystal p-n alkoxy benzoic acid. Here, optical properties: such as absorption coefficient, optical energy band gap, Urbach energy, and refractive index of supramolecular liquid crystals are measured for the denoised spectral data. The influence of hydrogen bonding and alkoxy chain length on the optical properties of liquid crystals has been deliberated upon. Further, the attempt at computation studies on the spectral data will yield important insights for subsequent investigations into UV-visible spectral data measurements.
