Sers spectra of mono and bisphthalocyanine complexes deposited on Ag and Au supports

Abstract : In this letter, we present a study of surface-enhanced Raman spectra of thin layers of phthalocyanine (Pc) complexes deposited on Ag and Au rough surfaces. The materials of this work are MgPc (monophthalocyanine) and the asymmetrical lutetium bisphthalocyanine (tBu)4PcLuPcCl8 (Pc′LuPc″) under three oxidation states. Enhancement of specific bands is observed depending on the surface and the oxidation state. SERS signatures of neutral, oxidised and reduced Pc′LuPc″ are identified.
