This paper describes interactions between metal complexes and self-ass
emblies of covalently bound ligand monolayers on surfaces. Covalently
bound molecular self-assemblies of (3-cyanopropyl) trichlorosilane (CP
TS) were anchored on the surfaces of fused quartz and the native oxide
of the [100] crystallographic orientation of p-doped Si wafers. The f
ormations of a number of ruthenium and osmium metal carbonyl complexes
on both the substrates and substrates coated with ligand monolayers h
ave been examined with polarized variable-angle internal attenuated to
tal reflection infrared spectroscopy (PVAI-ATR-IR). Both mononuclear s
pecies M(CO)(n)L (n = 2,3), where L = -(CH2)3CN, ana multinuclear spec
ies M3(CO)10(mu-CO)L were observed on the surface of the covalently bo
und, self-assembled ligand monolayers when the coated substrates were
treated with M3(CO)12, where M = Ru and Os. Ruthenium porphyrin macroc
ycle RuTPP(CO).THF which has a ''disklike'' structure was bound to a C
PTS axial ligand and then formed a covalently bound, self-assembled mo
nolayer of ''porphyrin-disk'' stacking on the quartz surface. This mon
olayer was analyzed by UV-vis spectroscopy and secondary ion mass spec
trometry (SIMS).
