Nakum, Kiran J. published the artcileThe influence of lateral hydroxyl group and molecular flexibility on the mesogenic behavior of a new homologous series based on thiophene-chalcone: Synthesis, characterization, crystal structure and DFT study, Name: 1-Bromododecane, the publication is Journal of Molecular Structure (2022), 132891, database is CAplus.
A new homologous series of rod shaped calamite liquid crystals, I [R = Et, decyl, octadecyl, etc.] based on thiophene-chalcone was prepared by condensation of 2-hydroxy-4-n-alkoxybenzaldehydes (n = 2 to 8, 10, 12, 14, 16, 18) with (E)-1-(4-aminophenyl)-3-(thiophen-2-yl)prop-2-en-1-one. FT-IR, 1H NMR, 13C NMR and mass spectroscopy were used to characterize synthesized compds I. The liquid crystal behavior of all synthetic compounds I was investigated using Differential Scanning Calorimeter (DSC) and Polarizing Optical Microscope (POM). Lower members of the homologous series, n-heptyloxy to n-dodecyloxy , were nematogenic, and higher members, n-tetradecyloxy to n-octadecyloxy , were smectogenic, whereas n-ethoxy to n-pentyloxy derivatives were non-mesogenic, and n-hexyloxy exhibited monotropic nematic phase. The n-pentyloxy derivative crystallized under monoclinic, space group P2/c with unit cell dimensions a = 16.1723(9) Å, b = 5.8603(3) Å, c = 22.4320(12) Å, β = 100.153(2) , V = 2092.69(9) Å3. The ethoxy derivative was subjected to DFT (d. functional theory) level computations and complete geometric optimization utilizing B3LYP/6-311G (d, p) basis sets and results were compared with structurally similar compound
