Problems solved by technology

[0004] At present, there are many reports on the synthesis of silver thiol clusters of different dimensions, among which the number of zero-dimensional silver clusters is the largest, and the number of one-dimensional silver clusters is less, but the two-dimensional structure formed by carbonate bridges has not been reported.

preparation example Construction

[0027] The preparation method of silver thion cluster material having luminescent properties is:

[0028] [AGS t Bu] n CF 3 Cooag, AGBF 4 (CH) 3 ) 4 NBR was dissolved in methanol, and the reaction was stirred, and the yellow suspension, wherein t BU means butyl, n BU refers to 正基基;

[0029] After filtration of the yellow suspension, the colorless transparent liquid was obtained, and the colorless transparent liquid was volatilized until a colorless block crystal was obtained.

[0030] Among them, [AGS t Bu] n CF 3 Cooag, AGBF 4 (CH) 3 ) 4 The molar ratio of NBR is 5.08: 2.09: 1.28: 1. For silver thion cluster materials, it is the key to the ratio of the reaction feedstock. Although the synthesis report of different dimensions of mercaptol, there are many synthesis reports of different dimensions, of which the number of silver clusters of zero-dimension is most, and less than one dimension. However, the two-dimensional structure formed by the carbonate bridge is not shown. In the p...

Embodiment 1

[0032] Example 1: Synthetic light-emitting silver cluster material

[0033] Under room temperature conditions, use analysis balance in turn [AGS t Bu] n (0.0657g, 0.334mmol), CF 3 COOAG (0.0303g, 0.1372mmol), AGBF 4 (0.0164G, 0.0842mmol) and (CH 3 ) 4 NBR (0.0101 g, 0.0656 mmol) was added to the glass reactor, and methanol was added as a solvent, and the magneton was added to the glass reactor and placed in a magnetic agitator, and dissolved in a suitable rotational speed, stirred, stirred after 24 hours after mixing The solution is yellow suspension (pH = 5.8 ~ 6.0);

[0034] After filtration of the yellow suspension, the colorless transparent liquid is filtered, and the colorless transparent liquid is stored in the beaker, slowly volatilized at room temperature, about a week of volatilizing colorless block crystals, ie a silver thion cluster material.

Embodiment 2

[0035] Example 2: Luminous spectrum research

[0036] Take the Silver Sulfur Cluster Material Sample Production Example 1, and the study of luminescence spectroscopy, due to D 10 The metal ion-centric compound has excellent luminescent properties, and therefore, the material is carried out in the solid and ethanol solution at room temperature. Such as Figure 6 As shown, the luminescent properties of solid compounds at room temperature are studied (eg Figure 6(a) shown in. The maximum emission peak at 298k and 370 nm excitation wavelength was 423 nm, and there was a weaker shoulder peak at both 485 nm and 506 nm. At the same time, the luminescence spectrum of the compound in the ethanol solution during 298k is also studied (eg Figure 6 (b) shown in (B), the result shows that the maximum emission spectrum is displayed at 433 nm at 365 nm excitation wavelength, and there is a shoulder peak at 410 nm, there is a weaker shoulder peak near 457 nm.

Description

Technical field [0001] The present invention discloses the technical field of inorganic nanomaterials, and more particularly to a silver thio cluster material having luminescent properties and a preparation method thereof. Background technique [0002] Because high-nuclear metal clusters have charming structures, such as planar polygons, metal rings, metal crown, paddle type, helical structure, wheene, sodaic, and cage structure, etc., in optical, electrochemical, magnetic, catalytic, ion There are potential application prospects in many areas such as exchange and selection, so countless chemical workers have been pursuing synthetic high-nuclear metal clusters. [0003] Many high-nuclear silver clusters of luminescent spectra and photoelectric performance have been reported that such illumination depends primarily on their structure and ligand properties. The charge transfer luminescence can be observed in the complex of the coin metal, which is produced from excited state to the...
