preparation example Construction

[0027] The preparation method of the above-mentioned silver-sulfur cluster material with luminescence properties is specifically:

[0028] [AgS t Bu] n 、CF 3 COOAg, AgBF 4 and (CH 3 ) 4 NBr was dissolved in methanol and reacted with stirring to obtain a yellow suspension, wherein, t Bu refers to tert-butyl, n Bu means n-butyl;

[0029] After filtering the yellow suspension, a colorless transparent liquid was obtained, and the colorless transparent liquid was volatilized until colorless massive crystals were obtained.

[0030] Among them, [AgS t Bu] n 、CF 3 COOAg, AgBF 4 and (CH 3 ) 4 The molar ratio of NBr is 5.08:2.09:1.28:1. For silver-sulfur cluster materials, the key lies in the ratio of the reaction raw materials. Although in the prior art, there are many reports on the synthesis of silver thiol clusters of different dimensions, among which the number of silver clusters in zero dimension is the largest, and the number of clusters in one dimension is less.

Embodiment 1

[0032] Embodiment 1: Synthetic luminescent silver cluster material

[0033] At room temperature, use an analytical balance to weigh [AgS t Bu] n (0.0657g, 0.3334mmol), CF 3 COOAg (0.0303g, 0.1372mmol), AgBF 4 (0.0164g, 0.0842mmol) and (CH 3 ) 4 NBr (0.0101g, 0.0656mmol) was added to a glass reactor, and methanol was added as a solvent, a magnet was added to the glass reactor and placed in a magnetic stirrer, stirred at a suitable speed to dissolve, stirred for 24 hours and then mixed The solution is yellow suspension liquid (pH=5.8~6.0);

[0034] After the yellow suspension is filtered through filter paper, a colorless transparent liquid is obtained. Store the colorless transparent liquid in a beaker and volatilize slowly at room temperature. After about a week of volatilization, a colorless massive crystal is obtained, which is the silver sulfur cluster. Material.

Embodiment 2

[0035] Embodiment 2: Luminescent Spectrum Research

[0036] Get the silver-sulfur cluster material sample that embodiment 1 makes, carry out the research of luminescent spectrum, because d 10 Compounds centered on metal ions have excellent luminescent properties. Therefore, at room temperature, the luminescent properties of this material in solid state and ethanol solution were studied. like Image 6 As shown, the luminescent properties of solid-state compounds at room temperature were studied (eg Image 6(a) shown). At 298K, the maximum emission peak at 370nm excitation wavelength is 423nm, and there are two weaker shoulders at 485nm and 506nm. At the same time, the luminescence spectrum of the compound in ethanol solution at 298K is also studied (such as Image 6 Shown in (b), the results show that: under the excitation wavelength of 365nm, the maximum emission spectrum is shown at 433nm, and there is a shoulder at 410nm, and a weaker shoulder near 457nm.

Abstract

The invention discloses a silver sulfur cluster material with a luminescent property and a preparation method and application thereof. The chemical formula of the silver sulfur cluster material is C101H184Ag34F30N2O39S16, and belongs to an orthorhombic crystal system, the space group is Pbac, and cell parameters are shown in the description. The silver sulfur cluster material is synthesized by adopting high-nucleus silver clusters modified by tert-butyl mercaptan, can be used for luminescent detection, and has the advantages that the preparation method is simple, the stability is high, and theluminescent property is excellent.

Description

technical field [0001] The disclosure of the invention relates to the technical field of inorganic nanometer materials, in particular to a silver-sulfur cluster material with luminescence properties and its preparation method and application. Background technique [0002] Due to the fascinating structures of hypernuclear metal clusters, such as planar polygons, metal macrocycles, metal crowns, paddle wheels, helical structures, rotaxanes, catenanes and cage structures, etc. Numerous chemists have been pursuing the design and synthesis of hypernuclear metal clusters because of the potential applications in many fields such as exchange and selection. [0003] The luminescence spectra and photoelectric properties of many high-nuclear silver clusters have been reported, and such luminescence mainly depends on their structures and the properties of their ligands. Charge-transfer luminescence is often observed in complexes of mint metals, resulting from the transition of electron...
