研究了四苯基卟啉金属配合物（ＭＴＰＰ，Ｍ＝Ａｇ，Ｍｇ，Ｃｕ，Ｐｄ）在ＡｇＩ胶体上的表面增强拉曼光谱（ＳＥＲＳ）。结果显示ＭｇＴＰＰ与基底发生金属交换生成ＡｇＴＰＰ，而在ＰｄＴＰＰ和ＣｕＴＰＰ上则未发现金属交换。除卟啉环的振动外，一些苯环振动带也被显著增强。在 １４００～ １６００ｃｍ－１范围，ＰｄＴＰＰ和ＣｕＴＰＰ的ＳＥＲＳ与ＡｇＴＰＰ有很大差别，可能反映了吸附分子在次甲基桥碳原子Ｃｍ附近立体构型的差异。
Surface-enhanced Raman spectroscopy (SERS) of tetraphenylporphyrin metal complexes (MTPP, M = Ag, Mg, Cu, Pd) on AgI colloids was investigated. The results show that metal exchange occurs between MgTPP and substrate to form AgTPP, while no metal exchange is found on PdTPP and CuTPP. In addition to the vibration of the porphyrin ring, some of the benzene ring vibration bands are also significantly enhanced. The SERS and AgTPP of PdTPP and CuTPP are very different in the range of 1400-1600 cm-1, which may reflect the difference of the configuration of the adsorbed molecules near the carbon atom Cm of the methine bridge.
