Treatment of the starting material (mu-PDT)Fe(2)(CO)(6) (PDT - SCH(2)CH(2)CH(2)S) with 4-diphenylphosphinoaminopyridine (PyNHPPh(2)) in the presence of the decarbonylating agent Me(3)NO center dot 2H(2)O afforded (mu-PDT)Fe(2)(CO)(5)(PyNHPPh(2)) (1) in 56% yield. Further treatment of 1 with Zinc tetraphenylporphyrin (ZnTPP) yielded the target light-driven model compound (mu-PDT)Fe(2)(CO)(5)(PyNHPPh(2))(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.
