Facile Synthesis of Dendritic Hydroxyl-terminated Cyanuric Chloride Derivatives and Their Properties

Novel dendritic compounds G1.5（OH）4 and G1.5（OH）8 with peripheral hydroxyl were synthesized under mild conditions from eyanuric chloride, ethylene diamine, ethanolamine and diethanolamine. The products could be separated and purified through dispersion and precipitation in organic solvents with good yields （over 93.0%） and high purity （above 98.0%, HPLC）. The structures of the products were characterized by 1R, MS, 1H NMR and elementary analysis. G1.5（OH）4 and Gl.5（OH）8 could be dissolved in polar solvents such as methanol, water and dimethylsulfoxide. TGA analysis showed that G1.5（OH）4 and G1.5（OH）8 had good thermo stability. The aqueous solutions ofG1.5（OH）4 and G1.5（OH）8 exhibited low surface tension.
