We demonstrated the impact of photo-switchable polarity on the guest accommodation in a Zr-based MOF containing azobenzene pendants (AzoMOF) . Upon exposure to light or heat, the azobenzene moieties in this AzoMOF exhibit a reversible and reproducible switching behavior in the crystalline nanopores. The prominent polarity alteration induced by cis/trans isomerizatons of azobenzene groups is visualized for the first time directly by using the polarity-sensitive dye erythrosine B as a molecular probe. This remarkable change of polarity in the crystalline nanopores is further reflected on the sorption events of CO2 in the AzoMOF. Our findings therefore shall provide a more profound understanding of the photochemical behavior of azobenzene moieties in porous crystalline materials.
