基于串联后合成策略，首次开发了一种新型的功能化MOF材料，Bronsted酸性离子液体（BAIL）被限制在定义明确的MIL-101纳米笼内。以苯甲醛与乙二醇的缩醛化反应为探针反应，考察了MIL-101负载BAIL的催化性能。BAIL/MIL-101纳米笼具有上级催化性能，这主要是由于离子液体催化剂的优点与MIL-101纳米笼中所需的微环境相结合。
A novel functionalized MOF material, Bronsted acidic ionic liquid (BAIL) confined inside well-defined MIL-101 nanocages, was developed for the first time based on the tandem post-synthetic strategy. The catalytic performance of BAIL confined in MIL-101 material was evaluated by using the acetalization of benzaldehyde with glycol as a probe reaction. The resulting BAIL/MIL-101 material exhibited superior catalytic performance, which is mainly due to the combination of the advantageous merits of ionic liquid catalyst with the desirable microenvironment in the MIL-101 nanocages.
