Energy transfer processes along a supramolecular chain of π-conjugated molecules.
We have investigated the energy transfer dynamics in a supramolecular linear polymer chain comprising oligofluorene (OF) energy donor units linked by quadruple hydrogen-bonding groups, and oligophenylene (OPV) chain ends that act as energy acceptors. Using femtosecond spectroscopy, we followed the dynamics of energy transfer from the main chain of OF units to the OPV chain ends and simulated th...

متن کاملInterference of Interchromophoric Energy-Transfer Pathways in π-Conjugated Macrocycles.
The interchromophoric energy-transfer pathways between weakly coupled units in a π-conjugated phenylene-ethynylene macrocycle and its half-ring analogue have been investigated using the nonadiabatic excited-state molecular dynamics approach. To track the flow of electronic transition density between macrocycle units, we formulate a transition density flux analysis adapted from the statistical m...
متن کاملSupramolecular Assemblies of Cucurbiturils with Photoactive, π‐conjugated Chromophores
Supramolecular assemblies of cucurbituril (CBn) homologues with p-conjugated chromophores will be overviewed. Special emphasis will be given to the effect of CBn on the optical properties of conjugated oligomers and polymers. How supramolecular complexes of p-conjugated chromophores including porphyrin derivatives, conjugated oligomers and polymers with CBn could be utilized in the theranostic ...
متن کاملUnderstanding the Assembly of π-Conjugated Dithiol Molecules on GaAs
Introduction The assembly of alkane-based molecular layers on metals (e.g. Au, Ag, Pt) and, to a smaller extent, on semiconductors (e.g. GaAs, Si) has been investigated in detail. Such chemistries, although potentially valuable in surface engineering and patterning, cannot facilitate charge transport on the molecular level due to their backbone saturation. On the other hand, π-conjugated system...
