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.
在本研究中，阳离子配合物[PtMe(MeSO)(dppf)]CFSO（PtFc）（dppf = 1,1'-双（二苯基膦基）二茂铁）被用作前体，以功能化多发色体系（吡啶基-卟啉基）苯（1）。制备了最终加合物[PtFc]-1，其含有十八个铂（II）有机金属[PtMe(dppf)]片段，并通过紫外/可见吸收、磷{1H}-核磁共振光谱和荧光发射进行了表征。紫外/可见和荧光滴定证实了铂（II）中心与卟啉外围取代基的所有吡啶基部分之间的配位。将[PtFc]-1的稀释二氯甲烷溶液滴铸到玻璃表面可得到微米级发光卟啉环。
