Paragraph 0036-0037, (2017/07/20)
The invention discloses a triazine compound, as well as a preparation method and application thereof. The novel triazine compound is prepared by taking 2,2'-dihydroxybiphenyl, phosphorus oxychloride, triethylamine and melamine as main raw materials, not only has a carbon source (biphenyl structure), but also has an acid source (phosphoric acid structure) and a gas source (melamine). The carbon forming agent has high carbon forming property, high thermal decomposition temperature, high stability and large residual carbon quantity. According to the preparation method provided by the invention, the reaction condition is mild, the side reaction is less, the operating flow is simple, the reaction cycle is greatly shortened, the used raw materials are safe and easily available, the use of an organic solvent is avoided because water serves as a reaction medium, the aftertreatment process is simplified, and industrialized production is facilitated. The solvent and the mother liquid can be recycled and reused, the operating flow of the process is simple, and the defects that the reaction time is too long and the use amount of the organic solvent is large in the existing process are overcome.
Polyethers with phosphate pendant groups by monomer activated anionic ring opening polymerization: Syntheses, characterization and their lithium-ion conductivities

This paper describes the preparations and lithium-ion conductivities of various solid polymer electrolytes for potential use in high-energy density lithium-ion batteries. The ring opening polymerization of epoxides (M1-M6), catalyzed by Zn(II), Cu(II) and Cd(II) complexes in the presence of tetrabutylammonium bromide (TBAB), yielded polyethers (P1-P6) in which phosphates were attached as pendant groups. A reaction condition where Zn(II) catalyst used slightly excess to TBAB increased the polymerization rate remarkably and yielded the polyethers with higher molar masses in a short time. These polymerizations proceeded following a "monomer activated anionic ring opening polymerization" mechanism. These living like polymerizations also progressed according to "formation of polymer chain per initiator" model. The solid-state lithium-ion conductivities of these polymers were examined using lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). The conductivity of one of the solid polymer electrolytes with 40 wt% of LiTFSI was 5.2 × 10-5 S cm-1 at room temperature and 2.9 × 10-4 S cm-1 at 80 C.

We recently reported the anti-cancer and anti-cytomegalovirus (CMV) activity of artemisinin-derived trioxane diphenylphosphate dimer 838. To probe the relationship between chemical structure and anti-CMV and anti-cancer activities, we now report synthesis and evaluation of a series of eight new dimer phosphate ester analogs of 838. This series of novel molecules was screened against human foreskin fibroblasts (HFFs) infected with CMV and against the human Jurkat T cell acute lymphoblastic leukemia cell line. This SAR study confirms the very high anti-CMV and anti-cancer potencies of dimer diphenyl phosphate ester 838 without its being toxic to normal cells.

Synthesis and properties of dibenzo(d,f)-1,3,2-dioxaphosphorepines of general formula X: O,S Y: viz.OH, SH, Cl R = 2.2'-biphenylylen are reported.The compounds with Y = OH or SH, which may be also named 2.2'-biphenylylenposphoric acids, form metal complexes in which, depending on the type of donor atom (S and /or O), the acid anion acts as a chelating or bridging ligand.
