Dicyano and pyridine derivatives of ß-carotene: synthesis and vibronic, electronic, and photophysical properties
(American Chemical Society, 2011-02-17)Density functional theory and time-dependent density functional theory calculations provide pictures of the molecular orbitals involved in the ground and excited states of two cyano derivatives of 8′-apo-β-caroten-8′-al ... -
Energy transfer followed by electron transfer in a supramolecular triad composed of boron dipyrrin, zinc porphyrin, and fullerene: a model for the photosynthetic antenna-reaction center complex
(American Chemical Society, 2004-06-30)The first example of a working model of the photosynthetic antenna-reaction center complex, constructed via self-assembled supramolecular methodology, is reported. For this, a supramolecular triad is assembled by axially ... -
Enhanced photocurrents via redox modulation by fluoride binding to oxoporphyrinogen in a zinc porphyrin-oxoporphyrinogen surface modified TiO2 supramolecular solar cell
(Royal Society of Chemistry, 2011-06-07)A novel approach for improving photocurrent in a supramolecular solar cell, composed of zinc porphyrin-oxoporphyrinogen (ZnP-OxP) surface-modified TiO(2), by redox tuning through fluoride anion binding to the redox active ... -
Face-to-face pacman-type porphyrin-fullerene dyads: design, synthesis, charge-transfer interactions, and photophysical studies
(John Wiley and Sons, 2008-01-01)Pacman-type face-to-face zinc-porphyrin-fullerene dyads have been newly synthesized and studied. Owing to the close proximity of the donor and acceptor entities, strong pi-pi intramolecular interactions between the porphyrin ... -
Photoinduced electron transfer in a Watson-Crick base-paired, 2-aminopurine:uracil-C60 hydrogen bonding conjugate
(Royal Society of Chemistry, 2007-02-07)A fluorescent reporter molecule, 2-aminopurine was self-assembled via Watson-Crick base-pairing to a uracil appended fullerene to form a donor-acceptor conjugate; efficient photoinduced charge separation was confirmed by ... -
Photosynthetic antenna-reaction center mimicry: sequential energy- and electron transfer in a self-assembled supramolecular triad composed of boron dipyrrin, zinc porphyrin and fullerene
(American Chemical Society, 2009-07-30)A self-assembled supramolecular triad, a model to mimic the photochemical events of photosynthetic antenna-reaction center, viz., sequential energy and electron transfer, has been newly constructed and studied. Boron ... -
Photosynthetic reaction center mimicry: low reorganization energy driven charge stabilization in self-assembled cofacial zinc phthalocyanine dimer-fullerene conjugate
(American Chemical Society, 2009-07-01)By employing well-defined self-assembly methods, a biomimetic bacterial photosynthetic reaction center complex has been constructed, and photoinduced electron transfer originating in this supramolecular donor-acceptor ... -
Plausible molecular mechanism for activation by fumarate and electron transfer of the dopamine beta-mono-oxygenase reaction
(American Chemical Society, 2002-10-01)A series of fumarate analogues has been used to explore the molecular mechanism of the activation of dopamine beta-mono-oxygenase by fumarate. Mesaconic acid (MA) and trans -glutaconic acid (TGA) both activate the enzyme ... -
Through-bond photoinduced electron transfer in a porphyrin-fullerene conjugate held by a Hamilton type hydrogen bonding motif
(The Royal Society of Chemistry, 2009-03-21)Control over the occurrence of through-bond electron transfer in self-assembled donor-acceptor conjugates is often difficult, since through-space electron transfer also competes due to the flexible nature of the spacer ...
