Abstract

H-bonded liquid crystals (HBLCs) are newly synthesized with PyBF viz., (4-pyridyl)-benzylidene-4′-fluoro aniline as the proton acceptor which is non-mesogenic and alkyloxy benzoic acids viz., nOBAs (n = 3, 12) as the mesogenic proton donors. The H-bond formed is confirmed by FTIR spectroscopy. Polarizing Optical Microscopy confirmed the H-bonded compound’s mesomorphic textures, and the thermal analysis is carried out using a Differential Scanning Calorimeter. The influence of fluorine atom on mesomorphic stability is studied. The nonlinear optical properties of the H-bonded compound is studied using DFT theoretical approach. This work supports the SDG-9 of the United Nations. Graphical abstract: (Figure presented.)
