开发了一种独特的主客体离子交换方法，用于制备纳米层状K(4)Nb(6)O（17）薄膜。3H(2)O同时具有(1)光学透明性和(2)在环境条件下离子交换性，在高温下不煅烧。以嵌入物MV(2+)-K(4)Nb(6)O（17）为前驱物，采用客体交换法制备了Ru(bpy)(3)(2+)-K(4)Nb(6)O（17）光响应电极杂化薄膜。采用x射线衍射、扫描电镜、原子力显微镜、红外光谱和紫外光谱以及元素分析对透明Ru(bpy)(3)(2+)-K(4)Nb(6)O（17）杂化薄膜进行了表征。研究了ITO/Ru(bpy)(3)(2+)-K(4)Nb(6)O（17）杂化薄膜电极的电化学行为；它在可见光区域也表现出快速的光响应。
A unique guest-guest ion exchange method was developed for preparing a thin film of a nano-layered K(4)Nb(6)O(17).3H(2)O that possesses both (1) optical transparency and (2) ion-exchangeability under ambient conditions without calcination at high temperature. An optically transparent Ru(bpy)(3)(2+)-K(4)Nb(6)O(17) hybrid thin film, a photoresponsive electrode, was successfully prepared by the guest-guest exchange method by use of the intercalation compound MV(2+)-K(4)Nb(6)O(17) as a precursor. The optically transparent Ru(bpy)(3)(2+)-K(4)Nb(6)O(17) hybrid thin films have been characterized by X-ray diffraction, SEM, AFM, IR, and UV spectroscopies, as well as elemental analysis. The electrochemical behavior of the ITO/Ru(bpy)(3)(2+)-K(4)Nb(6)O(17) hybrid thin film electrode was studied; it also exhibits swift photoresponse in the visible region.
