β-CyD (4.4 mmol) and a steroid as the template (1.5 mmol unless noted otherwise) were dissolved in dry DMSO (50 mL), and toluene 2,4-diisocyanate (TDI, 28 mmol) was added. After being magnetically stirred at 65 °C for 2 h, the gel formed was chopped into pieces, washed with acetone, and ground with mortar and pestle. The polymer was sufficiently washed with hot water, tetrahydrofuran (THF), and hot ethanol to remove the template molecule, β-CyD, and TDI. 小弟想請(qǐng)教文獻(xiàn)中提到的丙酮,熱水,四氫呋喃,和乙醇分別洗脫什么物質(zhì)? |
