Díaz Valenzuela, Carlos; Valenzuela, María Luisa; Ushak, Svetlana (Springer, 2008)A new silicated cyclotriphosphazene N3P3(O2C12H8)(2)(OC6H4Si(CH3)(3))(OC6H4Br) 1 has been synthesized and characterized. The solid state pyrolysis of 1 in air gives a nanostructured SiP2O7 3D network. The morphology of the ...
