Paragraph 0026; 0048; 0049, (2020/02/19)
The invention relates to an osmium complex as well as a preparation method and application thereof. The method comprises the following steps: adding ammonium chlorosmate and dipyridine into an organicsolvent, and performing a reaction so as to obtain a mixed solution; adding a reducing agent into the mixed solution, and performing a reaction so as to obtain an osmium complex precursor; and addingthe osmium complex precursor and 5-chlorine-2-benzodiazopyridine into ethylene glycol according to a preset ratio, performing a reaction under predetermined reaction conditions, and adding target anion, so as to obtain the osmium complex. The osmium complex provided by the invention has extremely high structural stability, barely emits fluorescence, has strong cytotoxicity to tumor cells, has selectivity to cancer cells, and can be applied in the field of Raman imaging of tumor cells.
Toward the Control of the Creation of Mixed Monolayers on Glassy Carbon Surfaces by Amine Oxidation

A versatile and simple methodology for the creation of mixed monolayers on glassy carbon (GC) surfaces was developed, using an osmium-bipyridyl complex and anthraquinone as model redox probes. The work consisted in the electrochemical grafting on GC of a mixture of mono-protected diamine linkers in varying ratios which, after attachment to the surface, allowed orthogonal deprotection. After optimisation of the deprotection conditions, it was possible to remove one of the protecting groups selectively, couple a suitable osmium complex and cap the residual free amines. The removal of the second protecting group allowed the coupling of anthraquinone. The characterisation of the resulting surfaces by cyclic voltammetry showed the variation of the surface coverage of the two redox centres in relation to the initial ratio of the linking amine in solution.
