Chiral network: Poly(phenylacetylene) chains were derivatized with chiral side chains and bulky pentiptycene groups to give interlocking optically active aggregates (see figure; A forms initially and the aggregate then tightens to form B) in both solution and solid state. The resultant grid is a stable organization with high optical activity, high quantum yields, and superior detection limits for trinitrotoluene.
