Deposition and Atomic-Force Microscopy of Individual Phthalocyanine Polymers Between Nanofabricated Electrodes
Individual chains of the rigid-rod polymer phthalocyaninepolysiloxane (PcPS) have been deposited and immobilized on top of nanofabricated metal electrodes. This is realized by embedding sparsely distributed PcPS polymers in a monolayer of cellulose using the Langmuir-Blodgett deposition technique. Atomic force microscopy was used to study the resulting spatial arrangement of these one-dimensional conducting polymers, Images of the polymer chains were obtained with a lateral resolution of better than 1 nm. Inspection of the polymers near the edges of the electrodes demonstrates that the monolayer structure is not perturbed by the 15 nm high electrodes. With this procedure, it appears to be possible to bridge two closely spaced electrodes with individual PcPS polymer chains.
