For the first time, an absolute quantification of hybrid materials obtained from the reaction of phenylphosphonic acid (PPA) with TiO2 nanoparticles under different reaction conditions is reported. Next to the amount of PPA involved in grafting to the TiO2 nanoparticles, also the PPA included in titaniumphenylphosphonate crystallites is described quantitatively. The quantitative analysis is based on solid state (31)P MAS NMR and is further applied to evaluate the stability of the resulting hybrid materials towards hydrolysis and organic solvent exposure.
首次报道了在不同反应条件下，苯基膦酸（PPA）与TiO₂纳米颗粒反应所得杂化材料的绝对定量分析。除了参与接枝到TiO₂纳米颗粒上的PPA量外，还对苯基膦酸钛微晶中所含的PPA进行了定量描述。定量分析基于固态³¹P MAS NMR，并进一步用于评估所得杂化材料对水解和有机溶剂暴露的稳定性。
