Embodiment 1
[0040] Embodiment 1, the preparation of porous organometallic polymer material POMP 1a:
[0041]
[0042] Add 1mmol of bisbenzimidazole nitrogen heterocyclic carbene iridium compound (0.63g) into a 50mL Schlenk tube, vacuum and change nitrogen three times, then add 10mL of 1,2-dichloroethane and 3mmol of benzene (0.23g) successively, and stir at room temperature After a period of time until the solids were completely dissolved, 9 mmol of dimethylformal (FDA, 0.68 g) and anhydrous ferric chloride (1.46 g) were added. After sealing, put the reaction system into an oil bath at 30-80 degrees to react for 1-72 hours. After the reaction was complete, it was cooled to room temperature, filtered, washed, and the obtained solid was extracted by Soxhlet for 24 hours, and vacuum-dried at 60° C. for 24 hours to obtain the porous organometallic polymer POMP1a. The TEM spectrum of the solid is attached figure 1 shown. Yield: 0.58 g, 60%.
Embodiment 2
[0043] Embodiment 2, the preparation of porous organometallic polymer material POMP 1b:
[0044]
[0045] Add 1mmol of bisbenzimidazole nitrogen heterocyclic carbene iridium compound (0.63g) into a 50mL Schlenk tube, vacuum and change nitrogen three times, then add 10mL of 1,2-dichloroethane and 3mmol of benzene (0.23g) successively, and stir at room temperature After a period of time until the solids were completely dissolved, another 12 mmol of dimethylformal (FDA, 0.91 g) and anhydrous ferric chloride (1.95 g) were added. After sealing, put the reaction system into an oil bath at 30-80 degrees to react for 1-72 hours. After the reaction was complete, it was cooled to room temperature, filtered, washed, and the obtained solid was extracted by Soxhlet for 24 hours, and vacuum-dried at 60° C. for 24 hours to obtain the porous organometallic polymer POMP1b. Yield: 0.70 g, 70%.
Embodiment 3
[0046] Embodiment 3, the preparation of porous organometallic polymer material POMP 1c:
[0047]
[0048] Add 1mmol of bisbenzimidazole nitrogen heterocyclic carbene iridium compound (0.63g) into a 50mL Schlenk tube, vacuum and change nitrogen three times, then add 10mL of 1,2-dichloroethane and 3mmol of benzene (0.23g) successively, and stir at room temperature After a period of time until the solids were completely dissolved, another 15 mmol of dimethylformal (FDA, 1.14 g) and anhydrous ferric chloride (2.43 g) were added. After sealing, put the reaction system into an oil bath at 30-80 degrees to react for 1-72 hours. After the reaction was complete, it was cooled to room temperature, filtered, washed, and the obtained solid was extracted by Soxhlet for 24 hours, and vacuum-dried at 60° C. for 24 hours to obtain the porous organometallic polymer POMP1c. Yield: 0.83 g, 80%.
