View the Complete Patent at the US Patent & Trademark Office
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 (.alpha.-complement), (ii) a molecular design of the second compound (.beta.-complement), and (iii) a solvent system that promotes co-crystallization.
