Exploring the Scope of Macrocyclic "Shoe-last" Templates in the Mechanochemical Synthesis of RHO Topology Zeolitic Imidazolate Frameworks (ZIFs).

The macrocyclic cavitand is used as a template for the mechanochemical synthesis of 0.2@RHO-Zn() (0.2@ZIF-71) and RHO-Zn (ZIF-11) zeolitic imidazolate frameworks (ZIFs).

Microporosity of a Guanidinium Organodisulfonate Hydrogen-Bonded Framework.

Guanidinium organosulfonates (GSs) are a large and well-explored archetypal family of hydrogen-bonded organic host frameworks that have, over the past 25 years, been regarded as nonporous. Reported here is the only example to date of a conventionally microporous GS host phase, namely guanidinium 1,4-benzenedisulfonate (p-G BDS). p-G BDS is obtained from its acetone solvate, AcMe@G BDS, by single-crystal-to-single-crystal (SC-SC) desolvation, and exhibits a Type I low-temperature/pressure N sorption isotherm (SA =408.
