Abstract Novel meso ‐ or β‐derivatized porphyrins with a carboxyl group have been designed and synthesized for use as sensitizers in dye‐sensitized solar cells (DSSCs). The position nature of bridge connecting the porphyrin ring carboxylic acid show significant influences on spectral, electrochemical, photovoltaic properties these sensitizers. Absorption spectra phenylethynyl that both Soret Q bands are red‐shifted respect to those 6 . This phenomenon is more pronounced 3 4 , which...
A selective microwave irradiation annealing method for the preparation of efficient polymer photovoltaic devices is reported. The power conversion efficiency increases upon increasing time. In situ temperature probing suggests that microwaves could penetrate anode without any loss energy, whereas organic active layer and cathode were both heated. Furthermore, X-ray diffraction indicated enhanced degree crystallization chains.
Abstract The study of the electrochemical fluorescence switching properties conjugated copolymers containing fluorene, triphenylamine, and 1,3‐diphenylimidazolidin‐2‐one moieties is reported. polymers show high quantum yields, excellent thermal stability, good solubility in polar organic solvents. While polymer emits blue light under UV irradiation, intensity quenched upon oxidation. fluorescent behavior can be reversibly switched between nonfluorescent (oxidized) state strong (neutral) with...
By dropwise addition of a solution tricarboxamide-cored triphenylamine dendrimer G1 in THF into water (5 × 10−6 M), nanoparticles with average diameters 80 ± 20 nm were formed and collected by centrifugation. The particles show aggregation induced emission emit green light under photoluminescence conditions. can be fused together applying concept electrochemical curing; the are coupled through oxidation to form film. This method provides fast assembling process for constructing films few...
The amorphous-to-quasicrystalline phase transformation in a Zr65Al7.5Ni10Cu7.5Ag10 metallic glass has been investigated by monitoring the quasilattice constant and composition of quasicrystalline particles samples annealed vacuum at 663 K for various times. It is found that decreases with annealing time saturates after 90 min while zirconium silver contents differ from those remaining amorphous matrix. results provide evidence nonpolymorphous reaction.
Wheels on water? A waterwheel-shaped porphyrin pentamer has been synthesized by palladium-catalyzed cross-coupling reactions. The key intermediate is a boronate porphyrin, in which four boronic ester groups are directly attached to the meso-positions.
Abstract The synthesis of porphyrin dimer and monomer with an anthraquinone or diacetoxyanthracene unit has been achieved. electronic absorption spectra show that the anthracene‐bridged 2 strong coupling between two units as evidenced by significant band broadening whereas anthraquinone‐bridged 1 does not communication. Porphyrin shows overlapping 1‐e − oxidation processes at E 1/2 (ox1) = +0.94 (ox2) +1.01 V, corresponding to first electron abstraction from a waves +1.01, indicating no...
