Organic Framework

Using the “crystal sponge” approach, weak organic electron donor molecules were impregnated and evenly distributed in a crystal of a metal–organic framework (MOF), with the self-assembly of the donor–acceptor pairs with electron acceptor ligands. The nanopores of the MOF confined them and induced a charge transfer phenomenon, which would not occur between donor and acceptor molecules in a bulk scale.

Donor Acceptor

Development of the interplay between monomer sequence and supramolecular chemistry is critical if chemistry is to recapitulate the properties of proteins and nucleic acids in the synthetic world. We have created sequenced trimers of aromatic donor/acceptor units which participate in charge-transfer interactions, linked by phosphodiesters. Each sequence displays its own characteristic self-assembly, and moreover complementary sequences interact with each other to produce new nanostructures and emergent thermochromism. This finding paves the way towards new functional nanomaterials which make bio-analogous use of sequence to tune structure.
