title: Synthesis and properties of chiral liquid crystal compounds containing cinnamic acid groups

description: In this paper, eight new liquid crystal compounds containing cholesterol and camphoric acid as chiral agents were designed and synthesised, and the cinnamic acid group as a bridge bond is introduced into the system to make the synthesised liquid crystal compounds have certain optical properties with excellent liquid crystal properties. The structure of liquid crystal compounds was characterised by FT-IR, <sup>1</sup>H NMR and <sup>13</sup>C NMR. The liquid crystal phase behaviour of liquid crystal compounds was characterised by POM, DSC and TGA. The optical properties of liquid crystal compounds were tested by ultraviolet-visible spectroscopy. The influence of different carbon chain lengths on liquid crystal performance and selective reflection performance was explored. The synthesised liquid crystal compounds were observed to exhibit diverse liquid crystalline textures, distinct selective reflection colours, and high thermal stability, demonstrating favourable optical properties. These chiral compounds demonstrate significant application potential, offering a viable pathway for chiral optical material development.

title: Synthesis, characterisation, and study of unsymmetrical homologous series of nematogenic liquid crystal compounds possessing imine linkage

description: A novel homologous series of compounds with imine linkage has been synthesised. The structure of every proposed compound was elucidated using FT-IR, <sup>1</sup>H-NMR, <sup>13</sup>C-NMR, and elemental analysis. The prepared compound’s mesomorphic behaviour was observed using a polarising optical microscope. The transition temperatures and the phase transition enthalpy change data values were recorded using differential scanning calorimetry. Nematic phases were observed in heating and cooling cycles by varying terminal alkoxy chain length (<i>n</i> = 1–10, 12, 14, 16) at one side. The structure–property relationship was carefully studied to understand the effect of terminal alkyl chain length, lateral group substituent, and azomethine linkage on the mesomorphic properties. To assess the thermal stability of all prepared compounds, a thermogravimetry study was performed.

title: Rod-like liquid crystalline molecules with ring-fixed benzanilides

description: Rod-like liquid crystals (LCs) consist of a linear rigid core and flexible hydrocarbon chains, and the resulting LC properties are significantly affected by these chemical structures. In designing rod-like LCs, tertiary amides are rarely employed, owing to their stability in the <i>cis</i> conformation (bent shape), while secondary amides have been utilised because of their stability in the <i>trans</i> conformation (rod-like shape). In this study, we synthesised rod-like LCs incorporating ring-fixed benzanilides, in which the Ar-CO and amide bonds are fixed, denoted as <b>PBA[<i>n</i>]</b> (<i>n</i> = 5, 6, 7). Their properties were evaluated through polarised optical microscopy, differential scanning calorimetry, and wide-angle X-ray diffraction measurements. The findings indicate that the LC properties can be modulated by varying the ring size. Furthermore, single-crystal structural analysis revealed the molecular alignment potential enabled facilitated　by the ring-fixed benzanilide.

title: Liquid crystalline behaviour of Nickel(II) complexes derived from alkoxybenzoylhydrazide: synthesis, characterisation, and mesophase study

description: The Nickel(II) complexes of {N’-4(4’-alkoxybenzoyloxy)benzylidene}-3-(decyloxy)benzoylhydrazide was synthesised and characterised to investigate its structural and mesomorphic properties. The structure was confirmed by FT-IR, Elemental, <sup>1</sup>H-NMR, <sup>13</sup>C-NMR, and <sup>1</sup>H-<sup>1</sup>H COSY spectroscopy, which indicated successful coordination through the azomethine nitrogen and carbonyl oxygen atoms. To explore the impact of alkoxy chain length on mesomorphism, additional homologous compounds bearing longer alkyl chains (C8-C18) were also studied for their phase behaviour. Mesophase investigations were performed using polarising optical microscopy (POM) and differential scanning calorimetry (DSC). All complexes exhibited nematic liquid crystalline phases. The phase transition temperatures were found to vary systematically with increasing chain length, reflecting enhanced flexibility and packing behaviour within the molecular structures. DSC analysis supported microscopic observations, showing distinct endothermic and exothermic transitions corresponding to crystal-LC-isotropic and reverse transformations. The texture observed under POM confirmed the formation of nematic phases characterised by high mobility and birefringence. These findings underscore the critical role of molecular design, particularly terminal chain length, in tuning the liquid crystalline behaviour of metal-hydrazone complexes.

description: The average level of vulnerability amongst a country’s population against 2019 CO2-FFI emissions per- capita per country for the 180 countries for which both sets of metrics are available. Vulnerability information is based on two global indicator systems, namely INFORM and World Risk Index. Countries with a relatively low average vulnerability often have groups with high vulnerability within their population and vice versa. The underlying data includes, for example, information on poverty, inequality, health care infrastructure or insurance coverage.

description: Observed impacts on ecosystems and human systems attributed to climate change at global and regional scales. Global assessments focus on large studies, multi-species, meta-analyses and large reviews. Regional assessments consider evidence on impacts across an entire region and do not focus on any country in particular. For human systems, the direction of impacts is assessed and both adverse and positive impacts have been observed e.g., adverse impacts in one area or food item may occur with positive impacts in another area or food item. Physical water availability includes balance of water available from various sources including ground water, water quality and demand for water. Global mental health and displacement assessments reflect only assessed regions. Confidence levels reflect the assessment of attribution of the observed impact to climate change.
