Application:

1. Synthesize a new type of modified electrode

Pan Fei et al. Based on the "adsorption - catalytic - dissolved detection " mechanism, it proposed a COFS as the A new type of modified electrode is constructed by the method of combining the combination of one -step electrochemical deposition through the in -situ doping and one -step electrochemical deposition. Based on the branch -like COFS material and carbon nano -pipe ( CNTS ), it has the characteristics of structural similarities, and it is high COF-V/CNTS material of the new type of interspersed structure. Use 2, 3- sulfurol to modify it, introduce s adsorption sites, and synthesize the COF-SH/CNTS material Essence Finally, the load gold nanotchocomosis ( Aunfs ) is used to increase the sensitivity of the electrode and prepare a new Aunfs/COF-SH/CNTS/GCE electrode. The specific steps are as follows:

( 1 ) COF-SH/CNTS Preparation

Add 100 in the 25 ml pyrex tube Mg Cof-V/CNTS and 4 ml trifluorophene, N2 after replacement three times, perform ultrasound processing ( 10 min ) , Get a uniform dispersing solution. In the atmosphere of n2 , add 10 mg Aibn and 100 in the Pyrex tube Mg 2, 3- Tanliol, stir 48 H under the conditions of 80 ℃. After removing the Pyrex tube to cool to room temperature, the products obtained will be washed in turn through THF and ethanol, and 70 ° C dry twenty four H , get black brown COF-SH/CNTS .

( 2 ) Aunfs/COF-SH/CNTS/GCE preparation

Select THF as the best dispersion. Called 1 mg COF-SH/CNTS put it in the centrifugal tube, add 1 ml Thf and 0.05 ml nafion , a uniform dispersed liquid is obtained after ultrasound processing. Take 5 μL COF-SH/CNTS Differential droplets to the GCE surface after the decentralization liquid droplets, and dry it with the assistance of infrared lights to get COF-SH/ CNTS/GCE . The activated COF-SH/CNTS/GCE is placed in the 1 mmol L-1 hauCl4 solution, and the constant power level technology is used in -0.2 V 60 s under the conditions, and the surface of the electrode of the ultra-pure water, and after drying it naturally, you can get the .

2. Synthesize a series of new monocular, double-tooton nitrogen miscellaneous Capital ligands ( NHC ) replaced by [Fe-Fe] hydrogenase active center model cooperative span>

Wang Yanhong and others used (μ-dmedt) [Fe (CO) 3] 2 ( i , domedt = 2, 3- Alcohol) is a series of new single-toothed, double-tooton nitrogen miscellaneous rings ( NHC ) replaced by [Fe-FE] hydrogenation Enzyme active center model matches ( II , (μ-DMedt) [Fe (CO) 2] 2 [IM E (CH2) 2 IM E] , Im E &Nbsp; = 1- methylimazole -2- Aya; (Co) 5]} 2 [I me (CH2) 2 IM E] ;] IMes , iMes &Nbsp; = 1, 3- two (2, 4, 6- trianglene benzene group imidazole -2- samane; < span> v , (μ-DMedt) [Fe2 (CO) 5] IME , IME = 1,   3- Erxiamole -2- Aya; vi , (μ-dmedt) [Fe2 (CO) 5] IPR < /span>, IPR = 1, 3- two (2, 6- two-spiny phenyl imidazole -2 - Aya). Here are the synthesis of some matches:

( 1 ) The synthesis of the maternal cooperative i :

Under the nitrogen atmosphere, 100ml Schlenk bottle is added to the bottle ( 55ml ), Fe (CO) 5 ( 13.4g,   68.6mmol ) and 2, 3- sulfurite ( 2.77g, 22.7mmol ), stir back 29h (signaling Formula 2-1 ). Cooled to room temperature, under 140 ° C , decompression distillation removed the solvents. The residue is separated by the silicone column chromatography. The orthopedane was eluted, and the dark red solution was obtained, and the solvents were removed. The red powder was obtained.

( 2 ) The synthesis of II and III

Atmosphere, at room temperature, 50ml Schlenk bottle A Add imidazole salt ( 1 ) ( 160mg > 0.46mmol ),, Vacuum drying 30min . Another SCHLENK bottle B adds T-BUOK ( 184mg , 1.64mmol ), Vacuum nitrogen replacement, add THF ( 7ml ), stir until fully soluble, add the double -headed needle slowly to A , stir fully, stir fully , Reaction 3H . SChlenk bottle C Add I ( 77mg, 0.23mmol ), vacuum nitrogen replacement, add THF ( 7ml ), stir until fully dissolved, double -headed needle is transferred to A , stir up fully, and reflects 1.5h . Infrared spectrum monitoring response. After the response is complete, concentrated, vacuum dry, and the red solids obtained as less as possible Dichloromethane solvents are dissolved, and neutral oxide column chromatography is separated. Use CH2CL 2/ orthopatane ( 1/2 ) to elute, get the first red strap, concentrate the solvent to get the orange powder III ( 26mg , 29.0%). When using CH2CL 2/ orthopatane ( 1/1 ), the second red strap was available to condense the solvent to get the red powder II ( 11mg , 12.4%).
