Guest and anion dependent: Structural dynamism and luminescence of a cationic porous framework (see picture) are investigated by different analytical techniques, such as single-crystal-to-single-crystal structural transformation. The compound shows size-selective sorption of hydrophobic guest molecules, easy exchange of anions of the framework, and interesting anion-responsive luminescence.
