Polymer based nanocontainers have attracted a myriad of
interests due to their functional groups, mechanical stability, combining with
inner voids and large speci?c surface area. Preparation of polymer
nanocontainers with speci?c nonspherical geometric morphology, precisely
controllable structure, composition, and functionalities still remains a
signi?cant challenge. Here, we report a method that enables synthesizing
nonspherical polymer nanocontainers with di?erent morphologies and
properties by using anisotropic metal?organic coordination compounds as
templates. The preparation process is based on the stronger monomer’s
binding ability to metal cations than that to the organic linkers. The
correlation between the binding energy and the formation of the hollow
structure is calculated theoretically. Polymer nanocontainers with multiple
morphologies (such as octahedron, dodecahedron, etc.) are constructed by
expanding template materials. The as-prepared polymer nanocontainers exhibit active properties (biomedical and energy storage)
that derive from the intrinsic nature as well as further functionalization, suggesting promising candidates in thermo-chemo cancer
eradication, Li-ion batteries, and so on.
