Exciton coupling is of fundamental importance and determines functional properties of
organic dyes in (opto-) electronic and photovoltaic devices. Here we show that strong …

An extension of the essential states model is developed to investigate the absorption and
electronic properties of a highly dipolar merocyanine dye and double and quadruple π …

A simple streptomerocyanine with five methine carbons (Mc) has been used as a suitable
model system to investigate theoretically the optical properties in organized assemblies of …

A key issue for the application of π-conjugated organic molecules as thin film solid-state
materials is the packing structure, which drastically affects optical and electronic properties …

Two identical or different merocyanine dyes were tethered by a rigid diphenylacetylene
spacer unit that enables the folding of the two dyes into co-facially π-stacked structures in …

In this study, the optical properties and excited-state dynamics of the unique self-assembled
donor-acceptor (DA) merocyanine dye stacks from dimer up to octamer, prepared via dipole …

A series of merocyanine dye dimers tethered at different sites with spacers ranging from 0 to
5 methylene groups and the corresponding monomer have been synthesized. The …

A series of well-defined chromophore stacks is obtained upon self-assembly of merocyanine
and bis (merocyanine) dyes in nonpolar solvents. Careful design of the spacer moieties …

Unlike the Frenkel exciton model, the essential state model (ESM) for aggregates of donor–
acceptor (DA) chromophores accounts self-consistently for the effect of the reaction field on …

Exciton coupling is caused by interaction through space between the electric transition
dipole moments in different chromophores. This phenomenon is particularly well observed …
