[0028] Example 1 Organometallic complexes containing thiophene functional groups

[0029] Will H 2 btdc(0.005g, 0.02mmol) and Cd(NO 3 ) 2 ·6H 2 O (0.015g, 0.05mmol) was added to a high temperature resistant screw-top glass bottle with a volume of 5mL, added 0.75mL DMF, stirred with a magnetic stirrer to dissolve it, and then added 0.75ml C 2 H 5 OH, stir for 15 minutes until the metal salt is completely dissolved and the ligand is evenly mixed. The glass bottle is sealed and placed in an oven at 75°C, heated at this temperature for 2 days, and heated at 5°C·h -1 The cooling rate is slowly cooled to room temperature, and yellow lumpy crystals are formed. They are washed with N,N-dimethylformamide, filtered, and dried to obtain the target product, which is a metal organic complex containing thiophene functional groups. The yield is 58%.

Abstract

The invention relates to a metal organic complex containing a thiophene functional group and a preparing method and application of the metal organic complex. According to the technical scheme, Cd(NO3)2.6H2O, a ligand 2,2'-bithiophene-5,5'-dicarboxylic acid(H2btdc), a solvent N,N-dimethyl formamide and ethyl alcohol are added into a high-temperature-resistant spiral opening glass bottle, and stirring is carried out at the room temperature; the container is sealed and then put into an oven, and heating is carried out for 1-2 days at the temperature of 75 DEG C; the container is slowly cooled to the room temperature, and yellow transparent bulk crystals are obtained; the mixture is washed with N,N-dimethyl formamide, filtered and dried, and the target product is obtained. The prepared metal organic complex containing the thiophene functional group shows a good fluorescence characteristic and can be used for efficiently and selectively recognizing heavy metal zinc ions.

Description

technical field [0001] The invention relates to a porous metal-organic complex containing thiophene functional sites and its preparation method and application, in particular to the preparation and application of a porous metal-organic complex with zinc ion selective recognition function. Background technique [0002] In recent years, functional metal-organic framework materials have received considerable attention as a rapidly developing field, not least because of their great potential for practical applications. In photochemical reactions, the absorption and release of light energy is achieved through the transfer of energy from the reaction center to the electron-driving center in the light-harvesting compound. To maximize the efficiency of the energy transfer process, the relative orientation of the components in the light-harvesting compound is crucial. In order to simulate the process of photosynthesis, the synthesis of molecules also relies on the effective control ...
