A stable hierarchical porous metal–organic framework PCN-56 with abundant Lewis acid sites (denoted as Defective-PCN-56) was synthesized by the low-temperature synthesis-induced defect formation method. The existence of mesopore in structure was confirmed by N2 sorption isotherm and the successful encapsulation of large dye molecules. The Defective-PCN-56 has higher loading capacity toward anti-cancer drug Doxo compared with that ofnearly ideal-crystal(denoted as Ideal-PCN-56) synthesized at high temperature, showing potential application as drug carrier. The low-temperature synthesis-induced defect formation strategy presented here provides a new and facile way to synthesize stable MOFs with the combination of intrinsic micropore and additional mesopore as well as abundant Lewis acid sites.

案件回放:  有一年暑假,一位13岁的小姑娘去参加学校组织的暑期游泳队。一天游泳回来,教练把她送到离家100米远的地方,让她自己走回去。可从那天起,她再没有出现过。两年后,小姑娘的尸骨在野外被发现。尸体已经腐烂。当时在场的警察,都直着身子站在那里看,只有李昌钰蹲在地上看了一会儿,发现小姑娘的尸骨上少了三根骨头,旁边有一些狗毛。  各位训练有素、身经百战的小侦探们,如果你们在现场看到以上场景的话,会
