Embodiment 1

[0022] Embodiment 1 is based on Mn Ⅱ ribbon cross complex

[0023] (1) The preparation method is as follows:

[0024] 1. Mix 0.0060g (0.03mmol) of MnCl 2 4H 2 O and 0.0176g (0.06mmol) of organic aromatic diamine ligand 1,3-bis(4-aminophenoxy)benzene (L) were put into 25mL Erlenmeyer flask respectively, and MnCl 2 Add 5mL of absolute ethanol and 3mL of dichloromethane into 1,3-bis(4-aminophenoxy)benzene, heat and stir to dissolve them completely. MnCl 2 Pour the absolute ethanol solution of 1,3-bis(4-aminophenoxy)benzene into the dichloromethane solution, and add 3 drops of distilled water to shake and mix well; seal the Erlenmeyer flask and leave it at room temperature In 10 days, reddish-brown powdery crystals were obtained, and then the powdery crystals were washed, filtered and dried to obtain Ⅱ The crude product of the ribbon cross-complex, the yield was 88%.

[0025] 2, will get based on Mn Ⅱ 0.03g of the crude product of the ribbon cross-complex was dissolved in ...

Embodiment 2

[0028] Embodiment 2 utilizes based on Mn Ⅱ Fluorescence Activity of Ribboned Cross Complexes for Detection of Aromatic Nitro Compounds

[0029] Method: the Mn-based Mn prepared in Example 1 Ⅱ Ribbon cross-complex grinding. In 10mL of acetonitrile, add 0.0075mg based on Mn Ⅱ The band-shaped cross-complexes can be dispersed evenly by ultrasonic to form a suspension.

[0030] Take 13 suspensions and put them into 13 groups of fluorescence cuvettes respectively, then add organic solvents dichloromethane (DCM), 1,4-dioxane (Diox) to these 13 groups of fluorescence cuvettes respectively , diethyl malonate (DM), ethyl acetate (EA), ethanol (EtOH), cyclohexane (He), methanol (MeOH), petroleum ether (PE), benzene (PhH), sec-butanol ( 2BA), nitrobenzene (NB), 2-nitrotoluene (2NT) and 3-nitrotoluene (3NT), stirred evenly, and detected by fluorescence spectrometer. Under the condition that the excitation light wavelength is 300nm, the emission light wavelength is 366nm for detection....

Abstract

The invention relates to a MnII-based belt-shaped crossed compound as well as a preparation method and application thereof. The compound is characterized in that MnCl2.4H2O and organic aromatic diamine ligands are respectively put into conical flasks; absolute ethyl alcohol is added into an MnCl2 flask; dichloromethane is added into the organic ligand flask; heating stirring is performed for complete dissolution; then, the MnCl2 solution is poured into the organic ligand solution; a small amount of distilled water is added; concussion is performed for uniform mixing; finally, opening sealing and hole binding are performed; the materials stand at room temperature for 10 days to obtain reddish brown powder crystals; then, the small-particle crystals are washed, filtered and dried to obtain atarget product. The reddish brown blocky crystals suitable for X-ray single crystal diffraction experiments are obtained by diffusing dichloromethane into the saturated ethanol solution of the powdery crystals. The MnII-based belt-shaped crossed compound prepared by the method has fluorescence activity, and can be used for detecting toxic solvents of aromatic nitro compounds.

Description

technical field [0001] The present invention relates to a metal-organic complex material, in particular to a Mn-based Ⅱ Ribbon-shaped cross-complex materials. Background technique [0002] In the field of supramolecular chemistry, coordination compounds (also known as complexes, long ago known as complexes), as a kind of functional materials, have been widely studied. Some complexes with special structures and properties have attracted more and more attention from scientific researchers. The research results related to the complexes have been widely used in the fields of catalysis, agriculture, luminescence, medicine and electromagnetics. More importantly, the organic ligands in the complexes are variable, and their structures can be changed through certain group modifications, thereby changing their functions. The properties and functions of ribbon cross-complexes have attracted more and more attention from researchers. In order to better apply ribbon-like cross-complex...
