| Abstract: | The behaviof of two kinds of porphyrin derivatives,meso-5,10,15,20-tetra(4'-hydroxyphenyl)-porphyrin(T(4-HP))and meso-5-(4'-hydroxyphenyl)-10,15,20-triphenylporphyrin(HPTPP),absorbed on Ag sols was investigated by UV-vis spectra and surfcae enhanced Raman scattering spectra.There was obvious SERS effect when T(4-HP)P and HPTPP were adsorbed on the particle surface of the silver sol,meanwhile,a new peak located around 460 nm in absorption spectra was observed in our experiments.It was found that the two adsorbed porphyrin derivatives undergoing partial metal incorporation to form new compounds called"sittin-atop"(SAT)complexes.In addition,the differences in spectra of UV-vis absorption and SERS between T(4-HP)P and HPTPP were also discussed. |
