A new approach towards zeolitic tetrazolate-imidazolate frameworks (ZTIFs) with uncoordinated N-heteroatom sites for high CO2 uptake.

Successful development of a new synthetic approach towards zeolitic tetrazolate-imidazolate frameworks (ZTIFs) via combining tetrazolates into the zinc-imidazolate frameworks leads to new ZTIF materials (ZTIF-1 and ZTIF-2) with zeolite-type topologies and uncoordinated N-heteroatom sites, which exhibit high CO2 uptake capacity.
