Abstract:
Supramolecular topology dictates the fate of charge-transfer (CT) excitons in donor-acceptor assemblies. By tailoring the geometric connectivity of NDI-pyrene conjugates (NPCs), we control whether CT channels remain confined or segregate into parallel pathways. Confined topologies localize electron-hole pairs to form emissive CT states, while segregated double-cable architectures facilitate long-range charge migration for visible-light-driven H2 evolution. Comprehensive structural and photophysical analyses collectively reveal how topology transforms excited-state dynamics into distinct photochemical outcomes. This study highlights the design principle of using geometric confinement to link supramolecular assembly with photocatalytic function.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
