Sequence-complementarity dependent co-assembly of phosphodiester-linked aromatic donor-acceptor trimers.

We have created sequenced phosphoester-linked trimers of aromatic donor/acceptors which participate in charge-transfer interactions. Each sequence displays characteristic self-assembly, and complementary sequences interact with each other to produce new nanostructures and thermochromism. This paves the way towards new functional nanomaterials which make bio-analogous use of sequence to tune structure.
