Luminescent MTN-Type Cluster-Organic Framework with 2.6 nm Cages

摘要

From a basic tetrahedral Cu_4I_4 cluster, a new MTN-type cluster-organic framework (COZ-1) containing giant 6~45~(12) and 5~(12) cages was successfully constructed. The 6~45~(12) cage has an inner diameter of 2.6 nm and a large pore volume of 9.2 nm~3; these tetrahedral Cu_4I_4 clusters with bulky size offer new opportunities for not only the formation of 4-connected zeotype structures but also the integration of porosity and photoluminescent properties from both the cluster and the framework.
