Journal ArticleDOI
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
Expanded Theory of H- and J-Molecular Aggregates: The Effects of Vibronic Coupling and Intermolecular Charge Transfer.
TL;DR: This review outlines advances made in understanding the relationship between aggregate structure and photophysics when vibronic coupling and intermolecular charge transfer are incorporated.
Journal ArticleDOI
Fluorescent J‐type Aggregates and Thermotropic Columnar Mesophases of Perylene Bisimide Dyes
TL;DR: The high stability and bright fluorescence of the mesophase of several of the compounds make them promising for applications as polarizers or components in (opto)electronic devices.
Journal ArticleDOI
Extended dipole model for aggregates of dye molecules
TL;DR: A simple model for the calculation of interaction integrals between dye molecules in aggregates is shown to be in excellent agreement with the result of quantum-mechanical computations even at direct contact of the molecules.

TL;DR: The well-defined co-aggregated dyes presented here exhibit photoinduced electron transfer on subpicosecond time scale, and thus, these supramolecular entities might serve as valuable nanoscopic functional units.

Optical Properties of Molecular Aggregates. I. Classical Model of Electronic Absorption and Refraction
TL;DR: In this article, a theoretical model was developed to predict the absorption and refraction of an aggregate of monomer units (a molecular aggregate, molecular crystal, or polymer) at any frequency.

The Electronic Spectra of Aromatic Molecular Crystals. II. The Crystal Structure and Spectra of Perylene
TL;DR: In this article, a new crystalline form of perylene has been found and its crystal structure has been determined by the two-dimensional X-ray diffraction method, which is explained as a stabilization of the lowest excited singlet state by a charge-transfer resonance interaction between the molecules in a pair.

Hypochromism and other spectral properties of helical polynucleotides
TL;DR: In this article, the effect of exciton interaction and dispersion-force interaction on the oscillator strength of a double-stranded polyadenylic acid having the configuration of DNA has been investigated.
