NOVELTY - Constructing molecular knots with graphene electrodes involves selecting graphene, using Raman spectroscopy to analyze graphene and selecting graphene base. The graphene substrate is immersed in the molecular solution and drying out to obtain a graphene base covering the self-assembled monolayer. The graphene substrate is covered with self-assembled monolayer is placed on the sample stage of Bruker's scanning tunneling microscope fitted with a gold tip, and then inserted into the needle. The controller drives the lance tip toward the graphene base. USE - Method of constructing molecular knots with graphene electrodes (claimed). ADVANTAGE - The method enables to construct molecular knots with graphene electrodes with steady and reliability. DETAILED DESCRIPTION - Constructing molecular knots with graphene electrodes involves selecting graphene, using Raman spectroscopy to analyze graphene and selecting graphene base. The graphene substrate is immersed in the molecular solution and drying out to obtain a graphene base covering the self-assembled monolayer. The graphene substrate is covered with self-assembled monolayer is placed on the sample stage of Bruker's scanning tunneling microscope fitted with a gold tip, and then inserted into the needle. The controller drives the lance tip toward the graphene base. The molecule-gold-molecular-graphene asymmetric molecular junction is formed by the interaction between the molecule and the gold tip and the sample. An INDEPENDENT CLAIM is included for a method for measuring molecular conductance based on molecular sections, which involves: (A) applying voltage at two stages of the obtained molecular segments to obtain signals that vary with tip distance and collecting thousands of current-distance curves; and (B) obtaining two-dimensional histogram of the conductance and distribution frequency, and conductance characteristics of the peak is obtained by fitting the corresponding conductivity Gaussian value.
