Crystallographic Image Processing (CIP) is applied to experimental Scanning Tunneling Microscopy (STM) images of regular (2D periodic) arrays of organic molecules on noble metal substrates. The crystallographically averaged (surface) lattices, structural motifs, and plane symmetry groups of the arrays are determined. An assessment of the samples with the goal of utilizing highly symmetric molecular...
Langmuir-Blodgett (LB) films of copper (II) 1,4,8,11,15,18,22,25-octabutoxyphthalocyanine, nCuPc(OBu) 8 , (non-peripheral substitution) and copper (II) 2,3,9,10,16,17,23,24-octabutoxyphthalocyanine, pCuPc(OBu) 8 , (peripheral substitution), were fabricated and characterized by optical spectroscopy and scanning probe microscopy. The LB films were transferred onto hydrophilic substrates...
Polycrystalline samples of metal salts of [alpha ],[alpha ]-dicyano-p-toluoylcyanide (DCTC [minus] ) have been prepared. The Raman spectra of NaDCTC, CuDCTC, and AgDCTC are reported, as are the IR spectra of CuDCTC and AgDCTC. Comparison of these Raman spectra with that reported for DCTC [minus] in solution indicates...
