Room temperature liquid crystal of symmetric gallic trimer containing cyanuric core: synthesis and mesomorphism was written by Guo, Hongyu;Fang, Xiaoting;Yang, Fafu;Wu, Yamin. And the article was included in Liquid Crystals.Synthetic Route of C9H6Cl2N4 The following contents are mentioned in the article:
Three novel gallic monomer , dimer and trimer with conjugated cyanuric core were designed and synthesized by Schiff-base condensation mode in yields of 80-90%. Their structures were characterised by fourier transform IR spectroscopy, 1H NMR (NMR), electrospray ionization mass spectrometry and elemental analyses. Their mesomorphic behaviors were investigated by differential scanning calorimetry, polarising optical microscopy and X-ray diffraction. The gallic monomer has no mesomorphic property, but the dimer and trimer possess good mesomorphic properties. The trimer with high symmetry exhibited the typical hexagonal columnar liquid crystal at room temperature The temperature range of mesophase is as wide as 149°C (14-163°C). The results suggested that the more gallic units and sym. structures are favorable for excellent mesomorphic properties. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Synthetic Route of C9H6Cl2N4).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Synthetic Route of C9H6Cl2N4
