Two specific applications of arylboroxine chemistry will be described.  First, we report the synthesis and characterization of nanoscale phenylacetylene assemblies containing boroxine cores.  These highly conjugated materials were synthesized convergently with the boroxine core installed in the last step.  Secondly, we report the noncovalent modification of poly(4-vinylpyridine)-polystyrene copolymers by way of arylboroxine condensation onto the Lewis basic polymer sites.  The rapid access to tripodal molecular architectures and the noncovalent nature of the polymer functionalization are attractive features of the boroxine chemistry.
