complexes are very stable and excellent light-absorbing
compounds, owing to their highly conjugated frameworks. The metallopolymers
containing metalla-aromatic substructures consist of a new type of
functional polymer, because they exhibit characteristics of both metalla-aromatic
and polymeric units. Herein, we reported a corn-like cylindrical metallopolymer,
prepared from the controlled polymerization of N-isopropylacrylamide
(NIPAM) by a polyrotaxane-based macroinitiator, followed by postpolymerization
modification with a photothermal metalla-aromatic complex. The corn-like
shape of this metallopolymer was confirmed by transmission electron
microscopy (TEM). Combining the photothermal effect of the metalla-aromatic
unit and the thermosensitive property of PNIPAM, the corn-like metallopolymer
exhibits a NIR-responsive behavior and represents a new smart material.
