Hollow Ferrocenyl Coordination Polymer Microspheres with Micropores in Shells Prepared by Ostwald Ripening

From the inside out: Hollow ferrocenyl coordination polymer microspheres with microporous shells were prepared by a convenient and template-free approach. An Ostwald ripening mechanism is responsible for the formation of hollow cavities. The hierarchically hollow coordination polymer microspheres have potential applications in catalysis, drug delivery, and hydrogen storage.
