| Abstract (english) | The dataset contains experimental data for the compounds synthesized and discussed in the paper Chiral Cyanobiphenyl Dimers – Significance of the Linking Group for Mesomorphic Properties and Helical Induction. It includes NMR data for intermediates and final products, as well as WAXS data for the chiral and racemic compound CBCOO7CB. Complete synthetic procedures, chemical characterization of intermediates and final liquid crystal (LC) dimers, along with LC data, are provided in the Supplementary Information file. |
| Methods (english) | Synthetic procedures and chemical characterization of intermediate compounds and final LC dimers are given in the file - Supplementary information including molecular structures. 1H and 13C{1H} NMR spectra were recorded on a Bruker AV 300 and 600 spectrometers in CDCl3 or d6-DMSO. Chemical shifts (δ) are given in ppm and are referenced to TMS or the internal protic solvent. Coupling constants are given in Hz. Wide angle X-ray scattering measurements (WAXS) where recorded using an Anton Paar SAXSpoint 5.0 beamline machine comprising a primux 100 Cu X-ray source (λ = 0.154 nm) with a 2D EIGER2 R detector. Samples were held between Kapton tape. Temperature was controlled using an Anton Paar heated sampler with a range of -10 ° C to 120 °C and the samples held in a chamber with an atmospheric pressure of < 1mbar. Samples were initially held at 120 °C to allow for temperature equilibration across the sample and then slowly cooled while stopping to record the scattering patterns. Subtraction of both the general background and any contributions from the Kapton tape was conducted by measuring scattering from an empty Kapton tape sample holder. Both this background and the sample were normalized for sample transmission and corrected to absolute scattering intensity in order to directly subtract the background scattering. |
