These papers describe the preparation and characterization of polymer supramolecular assemblies of high stability due to their unique structure, which combines covalently-bonded two-dimensional sheets with inter-sheet hydrogen bonding to result in multilayered single crystal formation. These highly-ordered structures exhibit interesting thermochromic and third-order nonlinear optical properties.

Amphiphilic hexagonally-arranged nanochannel composites were prepared by the coincident crosslinking of hexagonally assembled amphiphilic taper-shaped lyotropic liquid crystalline moieties with the transformation of a poly(p-phenylenevinylene) precursor to poly(p-phenylenevinylene). The poly(p-phenylenevinylene) was then located within the hydrophilic channels formed from the inverse micelle-like arrangement of the tapered monomers. In addition to the unique nanocomposites prepared, the characterization of isolated conducting polymer chains is also of interest.

Such structures require a polymer chain with sufficient insoluble and soluble segment lengths to allow for core nucleation and corona formation. The stabilization of such an assembly may provide for very small core-shell particles.

J Am Chem Soc 1997, 119:6656-6665. The ability to accurately control the shell-crosslinked nanoparticle dimensions, including the particle diameter, the core diameter and the shell thickness, is demonstrated. This is critical for the application of these materials, especially with respect to the adaptation of these nanoparticles as biological mimics, where the size is important.

This paper reports the preparation of shell-crosslinked nanoparticles through condensation reactions of difunctional crosslinkers throughout the shells of polymer micelles. This is a significant advance in the ability to tailor the shell and surface properties, in terms of the extent of crosslinking, the crosslinker length, and the crosslinker composition, which each affect the shell permeability, shell thickness, surface polarity, etc.

This work demonstrated that even polymeric crosslinkers could be used to crosslink the shells of polymer micelles, while avoiding intermicellar reactions, to yield thick and highly flexible shell domains that may serve to prevent protein adsorption in biomedical applications.

The assembly of millimeter-scale components is demonstrated, driven by shape recognition and the minimization of liquid-liquid interfacial free energies to generate elaborate three-dimensional structures. Selective surface chemistry for the different facets of the components dictates the assembly process and the resulting geometric structures obtained.

J Am Chem Soc 1998, 120:11061-11070. The structural analysis of dendrimers and their supramolecular assemblies were characterized by X-ray analysis. Shape changes, modes of assembly and changes in the resulting supramolecular assemblies were observed for the dendritic structures, as a function of generation number. The detailed structural analysis is important for understanding the current dendritic structures and for the design of future materials.

This paper reports the preparation of polyimide nanofoams by the use of diblock copolymer phase separation, in which one of the block segments is thermally labile. Alternatively, thermally-labile highly-branched polymer additives provided pore formation within organosilicates. In each case, highly porous materials composed of a crosslinked matrix were produced. These systems serve as precedent for the production of nanoscaffolds, however, the goals differ slightly from the proposed structures, in that the pores were the minor component, of small size and limited connectivity.
