Abstract

Porosity enhancement assisted by an unusual gate opening has been realized in an exceptionally rigid ultra-microporous framework. The gate-opening has been attributed to the presence of symmetrically positioned Zn–O bonds of the Zn–oxalate units that facilitate subtle swiveling motion resulting in a drastic improvement (42%) in the CO₂ capacity without compromising the CO₂/N₂ selectivity.
