Problems solved by technology

[0007] A comprehensive analysis of domestic and foreign research shows that there are relatively few studies on organosilane-protected metal clusters, organosilane-protected manganese clusters are even rarer, and the reported organosilane-protected manganese clusters They are all obtained under an inert atmosphere such as nitrogen, and sometimes require harsh conditions such as extremely low temperature, so it is urgent to optimize and improve the preparation technology of organosilane-protected manganese clusters, and study a technical route with mild preparation conditions

Embodiment Construction

[0012] Technical scheme of the present invention is as follows:

[0013] A preparation method of a mixed-valent decanuclear manganese cluster compound protected by an organosilane ligand, comprising the following steps:

[0014] First, dissolve trialkoxysilane in alcohol solvent, add appropriate amount of alkali to adjust the pH value, and then reflux for a certain period of time, pre-hydrolysis polycondensation occurs to obtain a prepolymer, and then add acetonitrile and azamide of divalent manganese ion metal salt The mixed solution of methyl formamide is transferred to a reaction kettle and cooled to room temperature to obtain a mixed-valent decanuclear manganese cluster protected by organosilane.

[0015] Synthetic technical route of the present invention is as follows:

[0016]

[0017] Wherein: R` is phenyl or methyl. n is an integer (1, 2, 3 or 4).

[0018] According to the present invention, the aforementioned alcoholic solvent refers to an alcoholic compound cap...

Abstract

The invention relates to an organosilane ligand protected mixed valence ten-nuclear manganese cluster compound and a preparation method thereof. The preparation process comprises the following steps: dissolving alkali in an alcohol solvent, then adding trialkoxysilane containing a substituent group, carrying out reflux reaction, and carrying out prehydrolytic polycondensation to obtain a prepolymer; and then adding a metal salt solution of divalent manganese, transferring the mixture solution into a reaction kettle, heating, and carrying out solvothermal reaction to generate the organosilane protected mixed valence ten-nuclear manganese cluster compound. The invention also provides the mixed-valence ten-nuclear manganese cluster compound prepared by the method. The preparation method is realized through a solvothermal method, reaction conditions are easy to control, and the obtained manganese cluster compound is clear in structure and relatively high in purity, can be directly applied and has a huge application prospect.

Description

technical field [0001] The invention relates to a mixed-valent decanuclear manganese cluster compound protected by an organosilane ligand and a preparation method thereof, belonging to the technical field of nanomaterial synthesis. Background technique [0002] Mixed-valent manganese clusters have attracted extensive attention of researchers due to their interesting electronic structures, outstanding magnetic properties (single-molecule magnets), and catalytic properties. Since the first single-molecule magnet Mn in the 1990s 12 Since being successfully prepared, a series of polynuclear manganese clusters protected by different ligands, such as carboxyl groups, β-diketones, pyridine-alcohols, etc., have been successfully prepared and isolated. Organosilanes can form various oligomeric forms by hydrolytic polycondensation [RSiO 1.5 ]n (n=1, 2, 4.6, etc.), these organosilanes that have not formed a fully closed structure with oligomerization have multiple oxygen coordination...
