中位-四(4-N甲氧羰甲基吡啶)卟啉锌的表面增强拉曼光谱研究

The Surface Enhanced Raman Spectra Investigation of Zinc Tetrakis (4-N-methoxycarbonylmethylpyridyl) porphyrin

我们研究了水溶性的中位一四(4-N甲氧羰甲基吡啶)卟啉及其锌配合物的共振拉曼光谱和表面增强拉曼光谱。对其拉曼特征频率作了经验式的归属,同时还研究了溶液酸度对它的表面增强拉曼光谱的影响,并对其表面增强机理进行了初步探讨。

The Surface Enhanced Raman Spectra and Resonance Raman Spec- tra of meso-Tetrakis (4-N-methoxycarbonylmethylpyridyl) porphyrin 〔H_2T_(YNEAMS)PYP(4)〕and it's Zinc Complexes〔ZnT_(YNEAMS)PYP(4)〕are report- ed. The frequencies and band assignments are made by analogy to those for ZnTMPYP(4). PH-dependent SERS of ZnT_(YNEAMS)PYP(4)are presented. We have detected structural changes by solution pH.
