摘要

Ultra high vacuum scanning tunnelling microscopy and electron paramagnetic resonance spectroscopy were used to investigate ISL and TEMPOL piperidine nitroxides molecules deposited on the Au(111) substrate by the drop-cast method. The STM results suggest that both compounds form dense layers on Au(111) with high molecular mobility observed during imaging process. High resolution STM topographies of both compounds suggest a well-defined molecular order which can be ascribed to the presence of self-assembly mechanism during layers formation. The EPR results indicated that both compounds deposited on the Au(111) substrate were not reduced retaining their paramagnetic properties. The significance of the results obtained in the field of single spin detection is briefly outlined.
