Hybrid materials based on inorganic nanocrystals with organic polymers feature
peculiar and fascinating properties and various applications. However, there
is still a need for simple synthesis procedures that provide precise control over
the polymer/nanocrystal microstructure of these materials. Herein, a novel
organometallic approach to polymer-coated ZnO nanocrystals was developed.
The presented method merges the initial ring-opening polymerization of e-caprolactone
mediated by an organozinc alkoxide initiator and an air-promoted
transformation of the resulting macromolecular organozinc species. This onepot
procedure results in quantum-sized ZnO crystals with a core diameter of ca
3 nm coated by poly(e-caprolactone) covalently bonded to the surface. Overall,
the ability to create well-defined hybrid composites should provide a unique ability
to access various nanosystems.
