Fried thing, but fluorescent quenching degree difference of several nitro explosives for the material is little, without single-minded recognition capability (ginseng
See：Li J.-R. etc., J.Am.Chem.Soc., 2016,138,6204).Zang etc. once reports the luminous porous gold of a terbium
Belong to organic framework materials, result of study shows that the material has good selective enumeration method ability to TNP, but does not carry out its circulation
Regenerability research (referring to：Zang S.-Q. etc., Chem.Eur.J.2015,21,15705).Geng's love is net《Based on rigid virtue
Fragrant Carboxylic acid ligand MOFs design, synthesis and performance study》Disclose a kind of detection, base available for nitroaromatic
In N, the Cd-MOF materials of N '-two (3,5- dicarboxyphenyi)-Isosorbide-5-Nitrae-aphthalimide part, but it can not meet in water
TNP carries out the requirement of single-minded selectivity sensing identification.
In summary, in the prior art for for the luminous porous metals organic frame of nitro explosive detection in water
Single-minded selective enumeration method problem and recycling problem, still lack effective solution.
The content of the invention
In order to solve the above problems, the invention provides a kind of luminous porous metals organic frame new material and its preparation side
Method, a kind of luminous porous metals organic frame material of zirconium is synthesized using the organic carboxyl acid part of zirconium ion and phosphinylidyne-containing amine group

Embodiment 12
The experimental program as described in embodiment 10, other nitro explosives (TNT, RDX, 2,4-DNT, NB, NT) are entered respectively
Fluorescent quenching research is gone, fluorescence emission spectrum is shown in Fig. 5~9.Figure 10 is synthesized luminous porous metals organic framework materials
To different nitro explosive fluorescence response cylindricality comparison diagrams, it can be seen from fig. 10 that material of the present invention is to different nitros
The fluorescent quenching degree of explosive is different, and wherein that most pronounced effects is TNP, it is seen that material of the present invention explodes to different nitros
Thing has selective enumeration method ability.
MOF materials synthesized by the present invention are to nitro explosive (such as TNP, TNT, RDX, 2,4-DNT, NB, NT) table in water
Good fluorescence sense Detection results are revealed, its reason is：(1) nitro explosive has strong electrophilic nitryl group,
It is good electron acceptor, and metal-organic framework material is typically all good electron donor, therefore under illumination condition, can
To occur, from metal-organic framework material (electron donor), to the electronics transfer between nitro explosive (electron acceptor), (PET is imitated
Should), so as to cause fluorescent quenching.According to density functional theory (DFT) be calculated nitro explosive lumo energy order be
TNP>TNT>2,4-DNT>RDX>NB>NT (Figure 11), with fluorescent quenching efficiency TNP in this experiment>TNT>RDX>2,4-DNT>NB>
NT order is basically identical but not fully identical, and this shows that PET effects are not the single factors for determining fluorescent quenching efficiency.
(2) fluorescent quenching efficiency is also relevant with the number of nitro in nitro explosive molecule.Contain three in TNP, TNT and RDX molecule
Individual nitryl group, contain two nitryl groups in 2,4-DNT molecules, respectively contain a nitryl group in NB and NT molecules, therefore
Divided according to nitro number, fluorescent quenching efficiency general sequence is (TNP, TNT, RDX)>2,4-DNT>(NB, NT), this and experiment
As a result it is basically identical.
In addition, the MOF materials have the main reason for single-minded selective enumeration method to TNP：(1) TNP absorption spectrum and sheet
The emission spectrum for the metal-organic framework material reported in invention has a greater degree of overlapping, makes between the two to occur effectively
Resonance energy transfer (RET), and with the absorption spectrum of other nitro explosives is hardly overlapping or overlapping very little (Figure 12), because
This, the MOF materials show highest quenching efficiency to TNP.(2) compared with other nitro explosives, the hydroxyl in TNP molecules
Group can form strong hydrogen bond with the amide group of metal-organic framework material, effectively strengthen interaction and energy between Subjective and Objective
Amount transfer, further improves fluorescent quenching efficiency.Therefore, it is luminous synthesized by the present invention in cited nitro explosive
MOF materials not only show the fluorescent quenching efficiency of maximum to TNP, and degree is quenched apparently higher than other nitro explosives
(Figure 10), this shows that the material has single-minded selective enumeration method recognition capability to TNP.
Although above-mentioned the embodiment of the present invention is described with reference to accompanying drawing, model not is protected to the present invention
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need to pay various modifications or deformation that creative work can make still within protection scope of the present invention.
