Influence of exciton-phonon interaction on long energy transport in J-aggregates

TL;DR

This paper develops a theoretical model to understand how exciton-phonon interactions influence long-range energy transport in J-aggregates, highlighting the role of weakly interacting acceptors in facilitating energy transfer.

Contribution

It introduces a novel phonon-exciton interaction model to explain exciton width and energy transfer mechanisms in two-dimensional molecular assemblies.

Findings

Long-range energy transport is possible with weakly interacting acceptors.

The new model explains exciton width in J-aggregates.

Energy transfer efficiency depends on exciton-phonon coupling strength.

Abstract

This paper presents a theoretical model intended to address the question of energy transfer in two-dimensional molecular assemblies such as Scheibe aggregates. A new phonon-exciton interaction is introduced to explain the exciton width in J aggregates. It is shown that the long range energy transport can occur for weakly interacting acceptors.
