Series of novel 1,3,5-triazine-based triphenylene oligomers , and with large bridging polyaromatic core were designed and synthesized by simple procedures in high yields. Their structures were confirmed by FT-IR, 1H NMR, ESI-MS and elemental analyses. Their mesomorphic behaviors were studied by differential scanning calorimetry, polarizing optical microscopy and X-ray diffraction. 1,3,5-triazine-based triphenylene monomer has no mesomorphic property, but 1,3,5-triazine-based triphenylene dimer and 1,3,5-triazine-based triphenylene trimer possess excellent mesomorphic properties. The mesomorphic temperature range of compound was as wide as 180°. These studies indicated that the mesomorphic properties were determined by the numbers of triphenylene units. More units of triphenylene in the oligomers resulted in better mesomorphic properties. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Application In Synthesis of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Application In Synthesis of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine
