Mxene材料和吡咯类反应合成？Preparation of conducting CPG-PPy 14. CPG 7 (0.50 g) was added to a solution of 3-aminopropyltriethoxysilane 8 (0.47 ml, 2.0 mmol) in toluene (5 ml) and stirred overnight at room temperature. The resulting aminopropyl-functionalised CPG 9 was subsequently washed with toluene (20 ml), then dichloromethane (20 ml) and dried under suction to afford a white free flowing powder 9. Pyrrole-2-carboxylic acid 10 (0.22 g, 2.0 mmol), DCC 20 (0.62 g, 3.0 mmol) and DMAP 21 (0.02 g, 0.2 mmol) were then added to a solution of aminopropyl-functionalised CPG 9 in DCM (20 ml) and the resulting reaction mixture stirred at room temperature, under N2 for 3 days. The reaction mixture was filtered under suction, washed with DCM (50 ml), then THF (50 ml) and dried to afford a pale yellow flowing powder 11. To enable polymerisation of the immobilised pyrrole moieties, pyrrole 13 (0.05 mL, 0.72 mmol) was added to the CPG-Py 14 and stirred with aq. Na2S2O8 12 (3.0 ml, 4.0 mM) for 2 h. The CPG-PPy 14 was filtered under suction, washed with DI water (50 ml), THF (50 ml) and finally DCM (50 ml) to afford a free flowing grey powder 14. Analysis of the material by IR spectroscopy (u = 1675 cm-1 ) confirmed the presence of pyrrole functionality查看更多
