Microporous B←N framework: A stable and efficient material for separating C2H2 and CO2

Instability of the microporous B←N framework (BNF) under thermal/vacuum activation is a critical issue hindering its development and application. In this issue of Chem, Zhang et al. exploit the asymmetry of the building units to construct microporous, stable interlocking structures that are highly effective at separating C2H2 from CO2 at ambient temperature.
