Three new kinds of self-assembled films were first fabricated through a new strategy. These films have Sn4 , Zr4 and Ce4 as bridging central ions, 3, 4, 9, 10-perylene tetracarboxylic acid (PTA) as functional molecules and oxalic acid as connecting ligand. All films were characterized by contact angle, UV spectra, X-ray photoelectron spectra (XPS) and cyclic voltammetry. The effects of light intensity, bias voltage, and electron donor on photocurrents of these films were also studied. 相似文献

本文通过三种金属离子桥联的方式制备了一系列cis-RuL2(SCN)2
(L代表4,4’二羧基-2,2’联吡啶)自组装膜,并利用接触角,UV光谱,循环伏安法以及XPS对自组装功能膜进行了表征。通过对其光致电子转移特性的详细研究,得到了最大阳极稳定光电流为1773-1843
nA/cm2,最大量子产率为3.2%。入射光强,偏压以及电子给体对体系性能的影响也进行了研究。研究结果表明不同的金属离子桥联在自组装膜上能显著地改善电子传输特性。桥联金属离子在自组装膜中能同时起到功能和结构的两种作用。这种自组装的成膜方式提供了一种非常好的修饰此类相似体系的新途径。 相似文献
