Electron and excitation transfer in hetero-supramolecular assemblies and at molecule-nanoparticle interfaces

Encapsulation of chromophores within Cram-type hemicarcerands allowed the investigation of fundamental photophysical phenomena, such as long-range triplet energy transfer, electron transfer, and the remote heavy atom effect. Furthermore, novel water-soluble hemicarcerands are being used to develop unique hybrid materials composed of semiconductor nanoparticles and host-guest assemblies. Photoinduced charge injection from the "incarcerated" guest into the conduction band of the semiconductor has been demonstrated.
