New organic dyes that contain variable lengths of conjugation featuring alternating thiophene and fluorene segments have been synthesized and efficient nano-crystalline TiO2 based dye-sensitized solar cells were fabricated using these molecules as light-harvesting sensitizers.
Titania nanoparticles sensitized with metal-free organic dye exhibit high visible-light activities for the redox conversion of water pollutants in a wider pH range in comparison with TiO(2) sensitized with ruthenium bipyridyl complexes.
Flame synthesis of hierarchical nanotubular rutile titania derived from natural cellulose substance.
Hierarchical nanotubular rutile titania material was fabricated by facile flame burning of ultrathin titania gel film coated cellulose nanofibres of commercial cellulose substance (filter paper), which possesses efficient photocatalytic performance for degradation of organic dye (methylene blue) under ultraviolet irradiation.
For the first time, we reported the strong electrogenerated chemiluminescence of organic dye, bis[4-(dimethylamino)phenyl]squaraine (BDPSQ), a high quantum yield and light-stable species, which might find applications in ECL analysis and imaging.
Two new truxene-based organic sensitizers (M15 and M16) featuring high extinction coefficients were synthesized for dye-sensitized solar cells employing cobalt electrolyte. The M16-sensitized device displays a 7.6% efficiency at an irradiation of AM1.5 full sunlight.
A new n-type semiconducting perylene bisimide dye has been synthesized that gelates a broad variety of organic solvents to afford well-defined nano- and mesoscopic helical fibers and bundles.
