Article cyanuric chloride as the main raw material of the triazine ring, and participate in the reaction when the different reactivities of the three chlorine atoms in its structure, and can control the characteristics of the condition stepwise, to prepare a series of novel containing all three triazine ring compounds by elemental analysis, infrared spectroscopy, nuclear magnetic resonance and other research methods to characterize their structures, and study the performance of its solubility, thermal stability. Specifically including the following contents: 1. Cyanuric chloride and p-nitrophenol as raw materials, the reaction temperature was controlled using aqueous acetone Preparation of 2,4,6 - tris (4 - nitrophenoxy) -1,3 , 5 - triazine. Using three different reducing method of nitro group reduction, to give 2,4,6 - tris (4 - Amino-phenoxy) -1,3,5 - triazine. Elemental analysis, 1H-NMR, IR The resulting products were characterized. Wherein the 2,4,6 - tris (4 - nitrophenoxy) -1,3,5 - triazine having good thermal stability, the initial decomposition temperature of 430 ° C. Preferably, the reducing effect of the Pd / C hydrazine hydrate the catalytic system, the reduction method of the selected three. Cyanuric chloride and 1,1 '- binaphthyl phenol as raw materials, NaOH as acid binding agent, cetyl trimethyl ammonium bromide as a phase transfer catalyst, and interfacial polycondensation preparing poly 2 - chloro -4 -1,1 '- binaphthyl-1 ,3,5 - triazine. By UV, fluorescence, IR, 1H-NMR and GPC, the polymer characterization; through TG, DSC thermal performance of the polymer; microscopic morphology of the polymer film was observed through an atomic force microscope. The results showed that the dichloromethane solution of this polymer can be formed on glass, and the emergence of nanometer pores. As raw materials. Cyanuric chloride and 4,4 - dihydroxy-azobenzene, NaOH as the acid binding agent, cetyl trimethyl ammonium bromide as the phase transfer catalyst, the interfacial polycondensation Preparation of poly 2 - chloro -4 , 4,4 '- azo-phenoxy-1 ,3,5 - triazine (PCCAB). NaOH as the acid binding agent in acetone aqueous solution of 4,4 '- dihydroxy-azobenzene 2 - anilino-4 ,6 - dichloro-1 ,3,5 - triazine was prepared by the reaction of 4,4 '- bis (anilino group is a chloro-triazinyl) the hydroxy azo benzene (DIATOB and). Their structures were characterized by IR, NMR, UV. Thermal Performance Analysis of the product by TG; tested by UV spectra of the light response performance of DIATOB; also observed between the two solubility, by comparing the results show, PCCAB even not dissolved in DMF, and the DIATOB can be dissolved in the majority common solvents.
