Abstract
Atomic force microscopy and X-ray reflectivity of metal-stearate (MSt) Langmuir–Blodgett films on hydrophilic Silicon (1 0 0), show dramatic reduction in ‘pinhole’ defects when metal M is changed from Cd to Co, along with excellent periodicity in multilayer, with hydrocarbon tails tilted 9.6° from vertical for CoSt (untilted for CdSt). Near edge X-ray absorption fine structure (NEXAFS) and Fourier transform infra-red (FTIR) spectroscopies indicate bidentate bridging metal-carboxylate coordination in CoSt (unidentate in CdSt), underscoring role of headgroup structure in determining morphology. FTIR studies also show increased packing density in CoSt, consistent with increased coverage.
