Global economic confidence and growth are linked to commodities invariably produced from catalytic and chemical separation technology relying on porous zeolitic materials. Zeolite with large pores and high thermal stability are much desired due to their wide applications in industry. However the synthesis of these materials remains elusive, which mainly hindered by the limited Si(Al)-O-Si(Al) bond length and angles available. Our ZIF strategy easily reticulates metal ions and tunable imidazolate linkers into nets of known and hypothetical zeolites having outstanding chemical and thermal stability comparable to oxide frameworks. Here, we report the departure of ZIF chemistry from the modern zeolite science with the discovery of two highly porous and thermally stable (up to 500oC) ZIF structures, ZIF-100 and ZIF-105 that have prodigious architectures never before observed nor predicted.
