Notes:
A convenient method for embedding organometallic complexes in polymer films has been developed and the FT-IR spectra of these films have been investigated at room temperature. Infrared data in the n̈(CO) stretching region are reported for M(CO)6 (M = Cr, Mo, W), CpMn(CO)3 (Cp = η5-C5H5), η-C6H6Cr(CO)2L [L = CO, P(n-Bu)3], (η6-C6H5NH2)Cr(CO)3, [η6-o-C6H4(NH2)MeCr(CO)3], CpFe(CO)LR [L = CO, PPh3; R = Me, C(O)Me] embedded in poly(methyl methacrylate) (PMMA), polystyrene (PS), polystyrene-poly(methyl methacrylate) (PS-PMMA), and polystyrene-polyacrylonitrile (PS-AN) plastic films. These matrices appear to approximate the common solvents ethyl acetate, toluene, toluene-ethyl acetate, and toluene-acetonitrile, respectively, with respect to n̈(CO) vibrational band behavior. Several of the films have been subjected to UV irradiation and the photoproducts formed have been identified by FT-IR spectroscopy. PS-AN effectively traps photogenerated coordinatively unsaturated species via coordination of its pendant nitrile groups.
