Dojindo,ODPA/100/O407,膦酸衍生物同样在金属氧化物上形成SAM

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 上的烷基膦酸酯 SAM 比三氯硅烷衍生物 SAM 作为有机晶体管的导体膜更有用13)。
