Rapid Synthesis of D-A'-π-A Dyes through a One-Pot Three-Component Suzuki-Miyaura Coupling and an Evaluation of their Photovoltaic Properties for Use in Dye-Sensitized Solar Cells

Twenty-four D-A'-π-A dyes were rapidly synthesized through a one-pot three-component Suzuki-Miyaura coupling reaction, which was assisted by microwave irradiation. We measured the absorption spectra, electrochemical properties, and solar-cell performance

New cyano-substituted organic dyes containing different electrophilic groups: Aggregation-induced emission and large two-photon absorption cross section

Three aggregation-induced emission active dyes (3a-c) were synthesized and their one- and twophoton absorption properties have been investigated. They were all found to be weakly fluorescent in THF solution, while they exhibited dramatic fluorescence enhancement in water/THF mixtures. The solid fluorescence of 3a-c was recorded and their fluorescence quantum efficiency (φf) values were determined to be 8.0%, 8.1%, and 16.4%, respectively. Moreover, the two-photon absorption (2PA) crosssections (σ) of 3a-c were measured and 3a showed the highest value of 702 GM The excellent aggregation-induced emission and 2PA properties provide a promising alternative for biophotonic materials.

HIGHLY-FLUORESCENT AND PHOTO-STABLE CHROMOPHORES FOR ENHANCED SOLAR HARVESTING EFFICIENCY

The invention provides highly fluorescent materials comprising a single (n=0) or a series (n=1, 2, etc.) of benzo heterocyclic systems. The photo-stable highly luminescent chromophores are useful in various applications, including in wavelength conversion films. Wavelength conversion films have the potential to significantly enhance the solar harvesting efficiency of photovoltaic or solar cell devices.

Synthesis and characterization of 2-alkylbenzotriazole-based donor-π-acceptor-type copolymers

Four donor-π-acceptor-type copolymers were synthesized via palladium-catalyzed Sonogashira coupling reaction. The resulting donor-π-acceptor-conjugated copolymers can show fluorescence emission in the range of λ = 473-568 nm, and the band gaps of the alternating polymers can be tuned in the range 3.09-3.74 eV by using four different donors.
