膦酸衍生物用于氧化金属的表面改性,如 Al2O31)、TiO22)、ZrO23)、SiO24)、Mica5)、不锈钢(SS316L)6)、镍钛诺7)、羟基磷灰石8)、AgO9)、ZnO10)、ITO11、12 ). 长期以来,有机硅烷一直被用于在金属氧化物上形成自组装单层 (SAM)。然而,由于试剂之间的稳定性和聚合性差,在应用中并不总是适用。另一方面,膦酸衍生物同样在金属氧化物上形成SAM,尽管它们是非常稳定的化合物。此外,据报道,膦酸衍生物使用形成比有机硅烷更稳定和致密的 SAM。克劳克等。人。和 Sekitani 等。人。显示 Al2O3 上的烷基膦酸 SAM 比三氯硅烷衍生物 SAM 更有用作为有机晶体管的导体膜 13)。11-HUPA 是一种含有羟基末端的烷基膦酸衍生物。普尔西弗等。人。通过控制用 11-HUPA12 修饰的 ITO 基板上的氧化条件来制备两种不同的表面图案(醛和羧酸)。
