Charge separation in nonfluorescent donor-acceptor dyad derived from boron dipyrromethane dye, leading to photocurrent generation

Article Abstract:

Boron dipyrromethene (BODIPY), which is commonly used as an energy absorbing and transferring antenna molecule, is modified to contain an electron donor moiety, 8-(2,45-trimethoxyphenyl)-4,4-difluoro-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene (MEOPHBDP). The photoinduced electron transfer from a 2,4,5-trimethoxyphenyl moiety to a BODIPY moiety of MEOPHBDP in acetonitrile was observed by femtosecond laser flash photolysis measurements.

Enhanced energy and quantum efficient of a nanocrystalline photoelectrochemical cell sensitized with a donor-acceptor dyad derived from fluorescein

Article Abstract:

The dye-sensitized photovoltaic is prepared by using donor-acceptor dyads derived from fluorescein. The photovoltaic measurements are performed using a standard two-electrode system consisting of a working electrode and a Pt sputtered electrode in air-saturated methoxyacetonitrile containing 0.5 M iodide and 0.05 M I(sub 2).

Hydrogen bonding effects on the surface structure and photoelectrochemical properties of nanostructured SnO2 electrodes modified with porphyrin and fullerene composites

Article Abstract:

The first mixed films of porphyrin and fullerene with hydrogen bonding on tin oxide (SnO2) as well as indium tin oxide electrolyte is reported to reveal efficient photocurrent generation. The results show that hydrogen bonding is a highly promising methodology for the construction of molecular photoelectrochemical devices.
