Spatial Control of 3D Energy Transfer in Supramolecular Nanostructured Host−Guest Architectures

Systematic control of 3D energy transfer (ET) dynamics is achieved in supramolecular nanostructured host−guest systems using spacer-functionalized guest chromophores. Quantum chemistry-based Monte Carlo simulations reveal the strong impact of the spacer length on the ET dynamics, efficiency, and dim...

Zusammenfassung:Systematic control of 3D energy transfer (ET) dynamics is achieved in supramolecular nanostructured host−guest systems using spacer-functionalized guest chromophores. Quantum chemistry-based Monte Carlo simulations reveal the strong impact of the spacer length on the ET dynamics, efficiency, and dimensionality. Remarkably high exciton diffusion lengths demonstrate that there is ample scope for optimizing oligomeric or polymeric optoelectronic devices.
