Unprecedented and highly symmetric (6,8)-connected topology in a porous metal-organic framework through a Zn-Ti heterometallic approach

The Zn(II)-Ti(IV) heterometallic approach is successfully adopted to produce a highly symmetric, binodal metal-organic framework with unprecedented topology in network solids. This material, ZTOF-2, possesses permanent porosity as shown by reversible sorption of various gases.This research was supported by the Basic Science Research Program through the National Research Foundation of Korea (2012R1A1A2004333).
