Porous β-cyclodextrin polymer (P-CDP). A flame dried 20ml scintillation vial equipped with a magnetic stir bar was charged with β-CD (0.200g, 0.176mmol), 1 (0.100 g, 0.500mmol), and K2CO3 (0.300g, 2.17mmol). The vial was flushed with N2 gas for 5min, then dry THF (8ml) was added and the vial was bubbled with N2 for additional 2–3min. The N2 inlet was removed and the mixture was placed on a hot stirring plate (85°C) and stirred at 500r.p.m. for 2 d. The orange suspension was cooled and then filtered, and the residual K2CO3 was removed by washing the solid on the filter paper with 1 N HCl until CO2 evolution stopped. The recovered light yellow solid was isolated and activated by soaking in H2O (2×10ml) for 15min, THF (2×10ml) for 30min and CH2Cl2 (1×15ml) for 15min. Finally, the solid was dried under high vacuum at 77K in a liquid nitrogen bath for 10min and then at RT for 2–3 days. 发自小木虫Android客户端 |
