Herein we report on the Si grafting of two Fe(4) derivatives, [Fe(4)(L(i))(2)(tmhd)(6)], in which tmhd is 2,2,6,6-tetramethylheptane-3,5-dionate and H(3)L(i) = R-C(CH(2)OH)(3) is a tripodal ligand with R = CH(2)= CH-CH(2)-O-CH(2) (H(3)L(i)) and CH(2)= CH-(CH(2))(9)-O-CH(2) (H(3)L(2)). These complexes were specifically designed to be directly anchored on the H-terminated silicon surface via the hydrosilylation reaction. The complexes were grafted by a one pot route based on the photoinduced hydrosilylation followed by a ligand exchange step in the same reaction solution. The resulting decorated surfaces were characterized using X-ray photoelectron spectroscopy (XPS), attenuated total reflection infrared spectroscopy (ATR-IR) and atomic force microscopy (AFM).
