J-aggregates: from serendipitous discovery to supramolecular engineering of functional dye materials.
TL;DR: This Review provides an overview on the J-aggregates of a broad variety of dyes created by using supramolecular construction principles, and discusses their optical and photophysical properties as well as their potential applications.
Journal ArticleDOI
Long-Range Resonance Energy Transfer in Molecular Systems
TL;DR: This review covers Förster theory for donor-acceptor pairs and electronic coupling for singlet-singlet, triplet-triplet, and superexchange-mediated energy transfer and includes the transition density picture of Coulombic coupling as well as electronic coupling between molecular aggregates (excitons).

Light absorption and structure of aggregates of dye molecules
TL;DR: In this article, the structures of aggregates of dye molecules are investigated on the basis of quantum-mechanical calculations, and a brick stone work arrangement is obtained instead of the ladder or staircase arrangement hitherto assumed.

Lichtabsorption von Farbstoff-Molekülpaaren in Sandwichsystemen aus monomolekularen Schichten
TL;DR: In this article, the absorption spectra of cyanine-like dye molecules in monolayer assemblies are investigated and pairs between two different dye molecules were obtained by superposing monolayers containing the first and second dye respectively.
