Constructing luminescent particle/MOF composites by employing polyvinylpyrrolidone-modified organic crystals as seeds†
Abstract
We develop a novel and facile chemical reaction route to modulate the crystallization process of luminescent zinc 8-hydroxyquinoline (Znq2) particles. Polyvinylpyrrolidone (PVP)-modified octahedral Znq2 micro- and nano-crystals were used as seeds to construct two distinct hybrid structures, i.e., Znq2@ZIF-8 core–shell and multiple Znq2 particles on each ZIF-8.
