Host-guest networks inclusion complexes

Figure 3 Schematic representation of the formation of inclusion complexes based on the recognition of a guest molecule by a host receptor (a), of a clathrate based on the inclusion of guest molecules within cavities generated upon packing of clathrands in the solid state (b), and of a 1-D inclusion molecular network named koilate formed through interconnection of hollow tectons (koilands) by connector molecules (c).

A novel approach should be credited to Luo and coworkers [65] to improve the SM performance of PCL. They prepared inclusion complexes between a-cyclodextrin and PCL. Through this host-guest complexation, a pecuUar physical network was created with naked PCL segments as switching phase and cyclodextrin-PCL inclusion complex domains as net points. Both R and R were shghtly reduced with the inclusion ratio (30-50%). The in vitro degradation of this new type of blend was faster than the reference PCL.
