Abstract This paper describes the preparation of metallo‐organic thin films of [FeTIM(CH 3 CN) 2 ] 2 + complex, where TIM stands for 2,3,9,10‐tetramethyl‐1,4,8,11‐tetraazacyclotetradeca‐1,3,8,10‐tetraene on oxidized silicon wafer, SiO 2 /Si, previously treated with 3‐imidazolilpropyltrimethoxysilane, 3‐IPTS. X‐ray photoemission lines of Fe 2p were used to probe the iron chemical environment in the physically and chemically adsorbed macrocycle complexes. As FeTIM can bind CO, NO or N ‐heterocycle, a built‐on Si wafer sensor device could be envisaged for these molecules. Copyright © 2004 John Wiley & Sons, Ltd.
