Abstract

In this study, the cationic complex [PtMe(MeSO)(dppf)]CFSO (PtFc) (dppf = 1,1'-bis(diphenylphosphino)ferrocene) was exploited as a precursor to functionalize the multi-chromophoric system (pyridyl-porphyrinato)benzene (1). The final adduct [PtFc]-1, containing eighteen platinum(II) organometallic [PtMe(dppf)] fragments, was prepared and characterized through UV/Vis absorption, P{H}-NMR spectroscopy, and fluorescence emission. UV/vis and fluorescence titrations confirmed the coordination between the platinum(II) center and all the pyridyl moieties of the peripheral substituent groups of the porphyrin. The drop casting of diluted dichloromethane solution of [PtFc]-1 onto a glass surface afford micrometer-sized emissive porphyrin rings.
