Abstract

The invention relates to a ruthenium complex monomolecular film and a method for preparing the ruthenium complex monomolecular film on HOPG (highly oriented pyrolytic graphite), and belongs to the technical field of molecule self-assembling chemistry. Pyrenyls in a ruthenium complex in a ruthenium complex monomolecular film and the HOPG with a Pi-electronic environment act with each other through Pi-Pi, and the two pyrenyls of the ruthenium complex are fixed on an HOPG interface; the general formula of the ruthenium complex is [Ru(Py4G2MeBip2)](PF6)2. The method comprises the steps of preparing a ruthenium complex solution, then performing surface treatment on the HOPG, and finally self-assembling the ruthenium complex on an HOPG substrate by a spinning method or an immersion method to prepare the ruthenium complex monomolecular film. The ruthenium complex monomolecular film is prepared by two methods, so that the prepared ruthenium complex monomolecular film has the advantages that the mechanical and chemical stability is high, and the thickness of the molecular film can be controlled and the like.

Description

technical field [0001] The invention relates to a ruthenium complex monomolecular film and a method for preparing the ruthenium complex monomolecular film on HOPG, belonging to the technical field of molecular self-assembly chemistry. Background technique [0002] The development of molecular self-assembly technology has brought new hope for the preparation and application of molecular devices. Monolayer films offer many scientifically and technically challenging opportunities for the study of molecular devices. The monolayer film self-assembly technology is to diffuse molecules in the solution to the substrate immersed in the solution, so that they undergo physical adsorption or chemical interaction to form an ordered molecular assembly system. Monolayer self-assembly is highly ordered and directional, and can interact with many groups, so a variety of surfaces with special interactions can be obtained through precise chemical control. [0003] Ruthenium complexes have ex...
