Embodiment 1
[0059] A preparation method of a phenyl-substituted triazine functionalized silsesquioxane-based hybrid porous polymer (3Ph-TSHPP), comprising the steps of:
[0060] (1) Add 0.189g of octavinylsilsesquioxane (OVS) with a cage structure, 0.524g of 2,4,6-tri (4-Bromophenyl)-1,3,5-triazine (3Ph-TA), 30 mL N,N-dimethylformamide, 0.138 g tetrakis(triphenylphosphine)palladium, 0.50 g sodium bicarbonate, room temperature Stir under low temperature for 30 minutes, then heat to 120°C, and react for 72 hours; Drying at 80° C. for 10 hours gave light yellow powder solid I (0.40 g, mass yield 93%).
[0061] (2) Soxhlet extract the obtained solid I with methanol and dichloromethane for 24 hours, and dry the obtained solid under vacuum at 80° C. for 24 hours to obtain 3Ph-TSHPP.
[0062] The specific surface area of the obtained 3Ph-TSHPP of the present embodiment is 555m 2 g -1 , the pore volume is 0.55cm 3 g -1 .

Embodiment 2
[0071] A preparation method of a thiophene-substituted triazine functionalized silsesquioxane-based hybrid porous polymer (3Th-TSHPP), comprising steps:
[0072] (1) Add 0.189g of octavinylsilsesquioxane (OVS) with a cage structure, 0.542g of 2,4,6-tri (5-Bromothiophen-2-yl)-1,3,5-triazine (3Th-TA), 30 mL N,N dimethylformamide, 0.138 g tetrakis(triphenylphosphine) palladium, 0.50 g bicarbonate sodium, stirred at room temperature for 30 minutes, then heated to 120°C, and reacted for 72 hours; The second time, drying at 80° C. for 10 hours under vacuum conditions gave brown yellow powder solid II (yield: 0.37 g, mass yield: 82%).
[0073] (2) Soxhlet-extract the obtained solid II with methanol and dichloromethane for 24 hours, and dry the obtained solid under vacuum at 80° C. for 24 hours to obtain 3Th-TSHPP.
[0074] The specific surface area of the 3Th-TSHPP product obtained in this example is 364m 2 g -1 , with a pore volume of 0.40 cm 3 g -1 .

Embodiment 3
[0083] A preparation method of a phenyl-substituted triazine functionalized silsesquioxane-based hybrid porous polymer (3Ph-TSHPP), comprising the steps of:
[0084] (1) Add 0.189g of octavinylsilsesquioxane (OVS) with a cage structure, 0.437g of 2,4,6-tri (4-bromophenyl)-1,3,5-triazine (3Ph-TA), 30mL N,N-dimethylformamide, 0.055g tetrakis(triphenylphosphine) palladium, 0.50g sodium bicarbonate, Stir at room temperature for 30 minutes, then heat to 120°C, and react for 72 hours; after the reaction, the reaction system is naturally cooled to room temperature, filtered with suction, and the obtained solid is washed three times with methanol, tetrahydrofuran, chloroform, and acetone respectively. Drying at 80° C. for 10 hours under vacuum condition gave light yellow powder solid III.
[0085] (2) Soxhlet extract the obtained solid III with methanol and dichloromethane for 24 hours, and dry the obtained solid in vacuum at 80°C for 24 hours to obtain 3Ph-TSHPP.
[0086] The speci...
