Examples
Embodiment 1
[0046] 1,4-Benzenediboronic acid (124.3 mg, 0.75 mmol), 2,4,6-tris(4-bromophenyl)-1,3,5-triazine (271.4 mg, 0.50 mmol), potassium carbonate ( 172.8 mg) and palladium acetate (7.0 mg) were sequentially added to a dry round bottom flask, then evacuated and replaced with argon three times. After the mixture was uniformly dispersed in dry, argon-saturated dimethylformamide DMF (40.0 ml), it was placed in a microwave reactor (MCR-3) and heated to 150° C. for 1 h. When cooled to room temperature, the mixture was filtered and the collected precipitate was rinsed several times with DMF and water, then stirred in the solution (water / methanol, 1 / 1, v / v) overnight, then with methanol at 70°C Soxhlet extraction for 48h and finally stirring in dichloromethane for 8h. The solid product was dried in an oven at 80° C. for 8 h to obtain a gray powder COP1 (180 mg, 45% yield). During photocatalytic methane oxidation, no liquid-phase products were detected.
Embodiment 2
[0048] Dipinamate 4,4-biphenyl diboronate (181.6 mg, 0.75 mmol), 2,4,6-tris(4-bromophenyl)-1,3,5-triazine (271.4 mg, 0.5 mmol) ), potassium carbonate (172.8 mg) and palladium acetate (7.0 mg) were successively added to the dry round bottom flask, which was then evacuated and replaced with argon three times. After the mixture was uniformly dispersed in dry, argon-saturated DMF (40.0 ml), it was placed in a microwave reactor (MCR-3) and heated to 150° C. for 1 h. When cooled to room temperature, the mixture was filtered and the collected precipitate was rinsed several times with DMF and water, then stirred in the solution (water / methanol, 1 / 1, v / v) overnight, then with methanol at 70°C Soxhlet extraction for 48h and finally stirring in dichloromethane for 8h. The solid product was dried in an oven at 80° C. for 8 h to obtain a gray powder COP2 (201.5 mg, 44% yield). During photocatalytic methane oxidation, no liquid-phase products were detected.
Embodiment 3
[0050] 1,4-Benzenediboronic acid (124.3 mg, 0.75 mmol), 1,3,5-tris(4-bromophenyl)-benzene (271.5 mg, 0.50 mmol), potassium carbonate (172.8 mg) and palladium acetate ( 7.0 mg) were sequentially added to a dry round bottom flask, then evacuated and replaced with argon three times. After the mixture was uniformly dispersed in dry, argon-saturated DMF (40.0 ml), it was placed in a microwave reactor (MCR-3) and heated to 150° C. for 1 h. When cooled to room temperature, the mixture was filtered and the collected precipitate was rinsed several times with DMF and water, then stirred in the solution (water / methanol, 1 / 1, v / v) overnight, then with methanol at 70°C Soxhlet extraction for 48h and finally stirring in dichloromethane for 8h. The solid product was dried in an oven at 80° C. for 8 h to obtain a gray powder COP3 (175 mg, 44% yield). During photocatalytic methane oxidation, no liquid-phase products were detected.
