Efficient Förster energy transfer from phosphorescent organic molecules to J-aggregate thin films

We demonstrate efficient Förster resonance energy transfer (FRET) from a thin film of phosphorescent dye, fac tris(2-phenylpyridine) iridium (Ir(ppy)3), to a thin film of J-aggregated cyanine dye, 5,6dichloro-2-[3-[5,6-dichloro-1-ethyl-3-(3-sulfopropyl)-2(3H)-benzimidazolidene]-1-propenyl]-1-ethyl-3(3-sulfopropyl) benzimidazolium hydroxide (TDBC). The measurement is performed on a planar sandwi...

Study of Sequential Dexter Energy Transfer in High Efficient Phosphorescent White Organic Light-Emitting Diodes with Single Emissive Layer

In this study, we report our effort to realize high performance single emissive layer three color white phosphorescent organic light emitting diodes (PHOLEDs) through sequential Dexter energy transfer of blue, green and red dopants. The PHOLEDs had a structure of; ITO(1500 Å)/NPB(700 Å)/mCP:Firpic-x%:Ir(ppy)3-0.5%:Ir(piq)3-y%(300 Å)/TPBi(300 Å)/Liq(20 Å)/Al(1200 Å). The dopant concentrations of...

Metal-organic framework materials for light-harvesting and energy transfer.

A critical review of the emerging field of MOFs for photon collection and subsequent energy transfer is presented. Discussed are examples involving MOFs for (a) light harvesting, using (i) MOF-quantum dots and molecular chromophores, (ii) chromophoric MOFs, and (iii) MOFs with light-harvesting properties, and (b) energy transfer, specifically via the (i) Förster energy transfer and (ii) Dexter ...

Highly efficient non-covalent energy transfer in all-organic macrocycles.

The use of aromatic organic macrocycles as supramolecular hosts for non-covalent energy transfer is reported herein. These macrocycles lead to stronger binding and more efficient energy transfer compared to commercially available γ-cyclodextrin. This energy transfer was particularly efficient for the highly toxic benzo[a]pyrene with a fluorescent BODIPY acceptor, with up to a 5-fold increase in...

Energy transfer in organic systems

T h e quantum efficiency of radiationless energy transfer from naphthalene to 9,lO-diphenylanthracene (DPA) and from 2,s-diphenyloxazole to D P A has been obsemed as a function of acceptor concentration in deoxygenated solutions in benzene, cyclohexane, cyclohexanol and benzenecyclohexanol mixtures. T h e results agree reasonably with the Yokota-Tanimoto relation for the effect of diffusion on ...
