摘要

This report presents experimental observations of dramatic variations in STM images of bis [1,3-di(p-n-tetradecyloxyphenyl)propane-1,3-dionato] copper(II) (abbreviated to C_(14)O-Cu) physisorbed on HOPG as the bias voltage is changed. Several representative image patterns were obtained for the rich changes of the internal contrast of the molecule. Submolecular features of the molecular cores and the interdigitated alkyl parts are clearly visible.
