Herein we report on the Si grafting of two Fe4 derivatives,[Fe4 (Li) 2 (tmhd) 6], in which tmhd is 2, 2, 6, 6-tetramethylheptane-3, 5-dionate and H3Li= R–C (CH2OH) 3 is a tripodal ligand with R= CH2CH–CH2–O–CH2 (H3L1) and CH2CH–(CH2) 9–O–CH2 (H3L2). 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 …
