5-羟基苯甲酸钠自组装单分子膜的取向（4-{8-[（11-巯基十一烷酰基）二茂铁基]辛氧基}苯基）-10，15，20-三苯基卟啉（PC 8 FcC 11 SH）分子，在此实现了具有有史以来报道的最高量子效率（>10%）的光诱导上山电子转移，研究了角分辨X射线光电子能谱（ARXPS）结合电化学覆盖测定。总厚度和Fe与PC 8 FcC 11 SH分子的SAM的最外部分之间的距离分别被确定为44和29 A，表明虽然PC 8 FcC 11 SH SAM的二茂铁羰基十一烷硫醇（FcC 11 SH）部分中的烷基链应该以约10 °的倾斜角取向。30°垂直于金表面，卟啉环的平面应几乎垂直于表面。这一结果表明，很高的光转换效率的最重要的原因之一是金和卟啉环之间的大分离。
The orientation of a self-assembled monolayer (SAM) of the 5-(4-{8-[(11-mercaptoundecanoyl)ferrocenyl]octyloxy}phenyl)-10,15,20-triphenylporphyrin (PC8FcC11SH) molecule on a gold substrate, at which a photoinduced up-hill electron transfer with the highest quantum efficiency (>10%) ever reported was achieved, was investigated using angle-resolved X-ray photoelectron spectroscopy (ARXPS) combined with an electrochemical coverage determination. The total thickness and the distance between the Fe and the outermost part of the SAM of the PC8FcC11SH molecule was determined to be 44 and 29 A, respectively, showing that while alkyl chains in the ferrocenecarbonylundecanethiol (FcC11SH) part of the PC8FcC11SH SAM should be oriented with a tilt angle of ca. 30° normal to the gold surface, the plane of the porphyrin ring should be almost surface-normal. This result suggests that one of the most important reasons for the very high photoconversion efficiency is the large separation between gold and the porphyrin ring...
