The Chameleonic Nature of Diazaperopyrenium Recognition Processes

摘要

Two broad classes (Scheme 1) of molecular recognition processes can be defined-namely, 1) homophilic recognition, which involves the interaction of structurally and electronically similar, if not identical, species, and 2) hetero-philic recognition in which constitutionally different species come together as a result of stabilizing intermolecular non-covalent bonding interactions. Nowhere are these concepts more relevant than when considering donor-acceptor recognition processes between 兾-electron-rich and 兾-electron-deficient species.
