Dojindo,FOPA/100/F329,膦酸衍生物同样在金属氧化物上形成SAM

Product Description

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)。Sharma 等。人。已经报道了通过氧等离子体处理或用含有全氟烷基的膦酸（FOPA）修饰ITO衬底来增加ITO衬底的功函数。然而，提高的功函数水平在 FOPA 改性衬底上保持 246 小时，而在氧等离子体处理的衬底上功函数立即降低 11)。此外，使用具有 FOPA 的改性 TO 制造的有机薄膜太阳能电池提高了光强度、驱动电压和寿命的稳定性。有三种不同烷基长度的全氟膦酸可供选择。
