Embodiment 1
[0036] 1. Take 20.00mg of [Cp*RhCl 2 ] 2 Put into a beaker, add 4mL of anhydrous methanol, red [Cp*RhCl 2 ] 2 Insoluble, suspended in methanol. Add 10.10 mg of 2,2'-bipyridine to the above suspension, and mix with [Cp*RhCl at 25°C 2 ] 2 After reacting for 2 hours, a metal complex was formed, and the red suspension gradually disappeared, forming an orange solution. The solution was heated in a water bath at 55 °C for 2 h to evaporate methanol, and the solution was concentrated to 1 mL. At 4°C, [Cp*Rh(bpy)Cl]Cl was gradually precipitated by adding anhydrous diethyl ether dropwise to the concentrated solution. Collect the precipitate and dissolve it in water, make a 3mM solution and store it at 4°C. [Cp*Rh(bpy)Cl]Cl is immediately hydrolyzed to generate [Cp*Rh(bpy)(H 2 O)] 2+ .
[0037] 2. Take 2 Erlenmeyer flasks, marked as Erlenmeyer 1 and Erlenmeyer 2;
[0038] Erlenmeyer flask 1: 250mL concentration is the bacterium suspension that the reactive red 2 solution of 50...
Embodiment 2
[0043] 1. Take 25.00mg of [Cp*RhCl 2 ] 2 Put into a beaker, add 3mL of anhydrous methanol, red [Cp*RhCl 2 ] 2 Insoluble, suspended in methanol. Add 15.00 mg of 2,2'-bipyridine to the above suspension, and mix with [Cp*RhCl at 30°C 2 ] 2 After reacting for 1.5h, a metal complex was formed, and the red suspension gradually disappeared, forming an orange solution. The solution was heated in a water bath at 60° C. for 1.5 h to evaporate the methanol, and the solution was concentrated to 1 mL. At 4°C, [Cp*Rh(bpy)Cl]Cl was gradually precipitated by adding anhydrous diethyl ether dropwise to the concentrated solution. The collected precipitates were dissolved in water and made into a 4 mM solution and stored at 4°C. [Cp*Rh(bpy)Cl]Cl is immediately hydrolyzed to generate [Cp*Rh(bpy)(H 2 O)] 2+ .
[0044] 2. Take an Erlenmeyer flask and prepare 250mL of reactive red 2 solution with a concentration of 50mg / L;
[0045] Rhodospirillum with a wet weight of 3 g was prepared into ...
Embodiment 3
[0050] 1. Take 20.00mg of [Cp*RhCl 2 ] 2 Put it into a beaker, add 5mL of anhydrous methanol, red [Cp*RhCl 2 ] 2 Insoluble, suspended in methanol. Add 10.10 mg of 2,2'-bipyridine to the above suspension, and mix with [Cp*RhCl at 20°C 2 ] 2 After reacting for 2 hours, a metal complex was formed, and the red suspension gradually disappeared, forming an orange solution. The solution was heated in a water bath at 65 °C for 2 h to evaporate methanol, and the solution was concentrated to 1 mL. At 4°C, [Cp*Rh(bpy)Cl]Cl was gradually precipitated by adding anhydrous diethyl ether dropwise to the concentrated solution. The collected precipitates were dissolved in water and made into a 4 mM solution and stored at 4°C. [Cp*Rh(bpy)Cl]Cl is immediately hydrolyzed to generate [Cp*Rh(bpy)(H 2 O)] 2+ .
[0051] 2. Take an Erlenmeyer flask and prepare 250mL of reactive red 2 solution with a concentration of 50mg / L;
