Embodiment 1

[0048] Embodiment 1 (synthesis of compound 1)

[0049] 2-Triphenylaminopyridine (0.9g, 5.6mmol) was dissolved in ether, and 1.6M t-Buli (6.56mL, 11.2mmol) was added dropwise at -78°C to react for 30 minutes. Still at -78°C, add PtCl dropwise 2 (Et 2 S) 2 (0.5g, 1.12mmol) in diethyl ether solution, after stirring for 30min, the temperature of the reaction system rose to 0°C. The organic phase was washed with saturated brine, extracted with dichloromethane, and dried over magnesium sulfate. The organic solvent was removed and separated by column chromatography to obtain the white target compound with a yield of 85%. The structure of the obtained compound is as image 3 Shown in 1.

Embodiment 2

[0050] Example 2 Compound 1 and CHCl 3 Interaction:

[0051] 1 mL of CHCl 3 Drop it on absorbent cotton, place it in a sealed fluorescent cell, cover it with a piece of clean absorbent cotton, put the quartz plate coated with compound 1 film on the surface, and monitor the change of its fluorescence signal with time at a wavelength of 420 nm, and its fluorescence time response curve like Figure 7 .

Embodiment 3

[0052] Example 3 Interaction of compound 1 with tribromomethane

[0053] Drop 1 ml of tribromomethane onto the absorbent cotton, place it in a sealed fluorescent cell, cover it with a piece of clean absorbent cotton, put a quartz plate coated with compound 1 film on the surface, and monitor the fluorescence signal at a wavelength of 420 nm over time , and its fluorescence time-response curve is as follows Figure 8 .

Abstract

The invention relates to a sensing material for detecting the halogenated hydrocarbon, which is characterized in that the center is the divalent platinum; the two ligands coordinated with the platinum are 2-phenylpyridine; and simultaneously, the phenyl is provided with the aryl substituent. The sensing material comprises platinum, 2-phenylpyridine ligands and aryl on the phenyl or oligomer and polymer further constructed by aryl. The aryl comprises the further constructed oligomer or polymer as well as ramification of aryl. The detection method is realized through detecting the change of the fluorescence intensity of the luminescent material by using fluorescence means. The provided luminescent material is applicable to the detection of the volatile halogenated hydrocarbon.

Description

technical field [0001] The invention relates to a platinum-centered luminescent material and method capable of sensing halogenated hydrocarbons, and its application in the detection of halogenated hydrocarbons. Background technique [0002] Dichloromethane, chloroform, carbon tetrachloride, 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2-trichloroethane, 1,1,2, Halogenated hydrocarbons such as 2-tetrachloroethane, tribromomethane, trichloroethylene, and tetrachloroethylene are commonly used organic solvents or chemical products. However, most of these halogenated hydrocarbons are toxic substances, especially their high volatility poses a great threat to the environment and human health. my country's "Dangerous Goods Archives in Sudden Pollution Accidents" has included 1361 kinds of toxic and harmful substances, of which 68 are listed as key pollutants, and 10 of these 68 key pollutants are halogenated hydrocarbons. Therefore, the rapid and sensitive detection of halogenat...
