Treatment of the starting material (μ-PDT)Fe2(CO)6 (PDT = SCH2CH2CH2S) with 4-diphenylphosphinoaminopyridine (PyNHPPh2) in the presence of the decarbonylating agent Me3NO·2H2O afforded (μ-PDT)Fe2(CO)5(PyNHPPh2) (1) in 56% yield. Further treatment of 1 with Zinc tetraphenylporphyrin (ZnTPP) yielded the target light-driven model compound (μ-PDT)Fe2(CO)5(PyNHPPh2)(ZnTPP) (2) in 94% yield. The new complexes 1 and 2 were characterized by elemental analysis, NMR, IR, and X-ray crystallography. The molecular structure of 2 revealed its precursor 1 and a photosensitizer ZnTPP joined together through axial coordination. Furthermore, the fluorescence emission spectra and electrochemistry were also investigated.
Graphical abstractA light-driven model compound has been synthesized from a complex [(μ-PDT)]Fe2(CO)5(PyNHPPh2) and a photosensitizer ZnTPP via axial coordination. The new complexes were characterized by elemental analysis, spectroscopies, and single crystal X-ray diffraction analysis.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► We prepared a light-driven model compound containing a photosensitizer zinc tetraphenylporphyrin and a [Fe2S2] cluster. ► The new complexes were characterized by elemental analysis and spectroscopies. ► The structures were determined by single crystal X-ray diffraction analysis.
