Cyanine dyes in solid state organic heterojunction solar cells
(2014-01-01)
Today numerous cyanine dyes that are soluble in organic solvents are available, driven by more than a century of research and development of the photographic industry. Several properties specific to cyanine dyes suggest ...
Optical and structural properties of cyanine dyes via electronic structure calculations
(2021-05-01)
Cyanine dyes are interesting compounds for diverse technological applications mainly because of their unique optoelectronic properties. Despite their interesting features, in general, structural and optical properties of ...
Photoinduced hole-transfer in semiconducting polymer/low-bandgap cyanine dye blends: evidence for unit charge separation quantum yield
(Royal Soc Chemistry, 2009-01-01)
Power-conversion efficiencies of organic heterojunction solar cells can be increased by using semiconducting donor-acceptor materials with complementary absorption spectra extending to the near-infrared region. Here, we ...

Strongly Red-Shifted Photoluminescence Band Induced by Molecular Twisting in Cyanine (Cy3) Dye Films
(2017-05-04)
Cyanine dye molecules, used as monomers or in aggregate form, find interesting applications in optoelectronic devices. Among the various aggregate species incorporating organic dyes, centrosymmetric dimers are known as ...
Vanadium oxide intercalated with polyelectrolytes: Novel layered hybrids with anion exchange properties
(Academic Press Inc Elsevier ScienceSan DiegoEUA, 2012)
Structure-behavior study of a family of "hybrid cyanine" dyes which exhibit inverted solvatochromism
(2016)
The inverted solvatochromism of twenty dyes containing an electron-donor phenolate conjugated with an electron-withdrawing nitro-substituted phenyl ring was analyzed in terms of the dye structure and substituents. Structural ...
NIR fluorescent biotinylated cyanine dye: optical properties and combination with quantum dots as a potential sensing device
(Royal Society of Chemistry, 2012-08-29)
We present a water soluble and fluorescent biotinylated probe derived from a carbocyanine dye. A high efficiency of energy transfer was measured when the dyes were placed on the surface of streptavidin conjugated Quantum ...
Polymethine cyanine dyes in beta-cyclodextrin solution: multiple equilibria and chemical oxidation
(JOHN WILEY & SONS LTD, 2010)
Absorption and fluorescence spectroscopy, electrochemical techniques, and semiempirical calculations were employed to characterize the multiple complexation equilibria between two polymethine cyanine dyes (IR-786 and ...
