Controlled Encapsulation of Functional Organic Molecules within Metal–Organic Frameworks: In Situ Crystalline Structure Transformation

Abstract

Functional organic molecules/metal–organic frameworks composites can be obtained by in situ crystalline structure transformation from ZIF‐L to ZIF‐8‐L under double solvent conditions. Interestingly, the as‐prepared molecules/ZIF‐8‐L composites with the leaf‐like morphology exhibit good fluorescence properties and size selectivity in fluorescent quenchers due to the molecular sieving effect of the well‐defined microporous ZIF‐8‐L.
