Modular and dynamic functionalization of polymeric scaffolds.

The design and synthesis of multifunctionalized, architecturally controlled polymers is a prerequisite for a variety of future applications of polymeric materials. On the basis of Nature's use of self-assembly in the creation of biomaterials, this Account describes concepts that were developed over the past 5 years that utilize noncovalent interactions such as hydrogen bonding, ionic interactions, electrostatic interactions, metal coordination, and pi-pi stacking in modification of copolymer side-chains to obtain multifunctional polymeric materials, induce polymer morphology changes, and influence bulk-polymer properties.

Self-assembly with block copolymers through metal coordination of SCS-Pd(II) pincer complexes and pseudorotaxane formation.

Poly(norbornene)-based block copolymers containing side chains of palladated pincer complexes/dibenzo[24]crown-8 or palladated pincer complexes/dibenzylammonium salts were synthesized. Noncovalent functionalization was accomplished with their corresponding recognition units through simple 1:1 addition with association constants (Ka) greater than 10(5) m(-1). The self-assembly processes were monitored by using both 1H NMR spectroscopy and isothermal titration calorimetry. In all cases, we found that the self-assembly of the recognition units along each polymer block does not preclude the self-assembly processes along the other block.

Supramolecular cruciforms.

By self-assembling fluorescent pyridyl cruciforms with bis-Pd-pincer complexes, supramolecular assemblies with attractive optical properties were synthesized; these assemblies show potential as electro-optical materials.
