Abstract

Rod-shaped and hexagon-like nanostructures of a phosphoric triamide 4-NO2C6H4C(O)NHP(O)(NHC(CH3)3)2 have been prepared by a sonochemical method and a microwave process, respectively. The new nano-structures were characterized by SEM, XRD, UV–vis, infrared spectroscopy, and elemental analyses. The crystal structure of compound showed a distorted tetrahedral geometry for phosphorus with anti-configuration for the P(O) and C(O) groups respect to each other. Non-covalent interactions, that is, hydrogen bonding, ππ stacking, and CH…HC contacts connected the chains into a 3D framework. Thermal stability in single crystalline and nano-scale was carried out by TGA and DSC. Further, P2O5 nanosphericals have been prepared from a precursor nano-rod phosphoric triamide at 750 °C with a diameter of 30–40 nm. P2O5 nanoparticles have been decorated from a single source precursor phosphoramide, 4-NO2C6H4C(O)NHP(O)(NHC(CH3)3)2, onto reduced graphen oxide surfaces by a solvothermal approach. Decorated nanoparticles have an orthorhombic phase with a sphere-like morphology and average size of 10–20 nm.

摘要

分别采用声化学法和微波法制备了棒状和六边形纳米结构的磷三酰胺 4-NO 2 C 6 H 4 C(O)NHP(O)(NHC(CH 3 ) 3 ) 2 . 新的纳米结构通过 SEM、XRD、UV-vis、红外光谱和元素分析进行​​了表征。化合物的晶体结构显示磷的扭曲四面体几何结构,P(O) 和 C(O) 基团相互之间具有反构型。非共价相互作用,即氢键,ππ堆叠和 CH…HC 接触将链条连接到 3D 框架中。通过 TGA 和 DSC 对单晶和纳米尺度的热稳定性进行了研究。此外,P 2 O 5纳米球已由前体纳米棒磷三酰胺在 750 °C 下制备,直径为 30–40 nm。P 2 O 5纳米颗粒已通过溶剂热法从单一来源的前体磷酰胺 4-NO 2 C 6 H 4 C(O)NHP(O)(NHC(CH 3 ) 3 ) 2修饰到还原的氧化石墨烯表面上. 修饰的纳米粒子具有球状形态的正交相,平均尺寸为 10-20 nm。
