Discovery of a novel, large pore phase in a bimetallic Al/V metal-organic framework

A new series of bimetallic COMOC-2(V)/DUT-5(Al) frameworks are developed and fully characterized. Electron paramagnetic resonance and transmission electron microscopy confirm the homogeneous dispersion of Al/V in the entire framework. The study of the flexibility by means of CO2 pressure dependent XRPD and high pressure sorption reveals the co-existence of two different large pore phases and a narrow pore phase in the entire pressure regime.A new series of bimetallic COMOC-2(V)/DUT-5(Al) frameworks are developed and fully characterized.
