Modular Supramolecular Approach for Co-Crystallization of Donors and Acceptors into Ordered Networks

摘要

Organic charge-transfer (CT) co-crystals in a mixed stack system are disclosed, wherein a donor molecule (D) and an acceptor molecule (A) occupy alternating positions (DADADA) along the CT axis. A platform is provided which amplifies the molecular recognition of donors and acceptors and produces co-crystals at ambient conditions, wherein the platform comprises (i) a molecular design of the first constituent (α-complement), (ii) a molecular design of the second compound (β-complement), and (iii) a solvent system that promotes co-crystallization.

主权项

1. An organic charge-transfer (CT) co-crystal consisting essentially of an electron acceptor molecule (A) and an electron donor molecule (D), wherein one of A and D is an α-complement and the other one of A and D is a β-complement, such that the β-complement is incorporated into the α-complement through molecular linkages in a solvent system to form a co-crystalline supramolecular network, wherein one or more of the molecular linkages between the α-complement and the β-complement use adaptive intermolecular recognition to form the one or more molecular linkages, the co-crystal characterized by having a crystal superstructure comprising a mixed stack lattice (DADADA) and a topological hydrogen-bonded network.
