Porous Lanthanide-Organic Open Frameworks with Helical Tubes Constructed from Interweaving Triple-Helical and Double-Helical Chains

摘要

In recent years,the construction of metal-organic coordination polymers has attracted considerable attention in supra-molecular and materials chemistry due to the formation of fascinating structures and potential applications as optoelectronic,magnetic,and porous materials.However,most of the work has so far focused on the assembly of the d-block metal-organic open frameworks,while the analogous chemistry of the lanthanides remains less developed.This is attributed to the tendency of the lanthanide ions for high coordination,which favors the formation of condensed structures with or without guest species.
