Molecular engineering of organic sensitizers with planar bridging units for efficient dye-sensitized solar cells

Here comes the sun: Three highly efficient organic sensitizers with sterically hindered fluorenyl units and planar indenothiophene derivatives were designed and synthesized (see figure). Devices based on one of these compounds, JK-303, gave overall conversion efficiencies of 8.69, 9.04, 7.27, and 5.82 % using I-/I3-, CoII/CoIII, polymer gel, and solid-state electrolytes, respectively. These efficiencies are some of the highest reported for DSSCs based on organic sensitizers. Copyright

Synthesis and luminescent properties of branched oligophenylenefluorenes

The spectrophotometric and luminescence studies on branched oligophenylenefluorenes have shown that the incorporation of n-octyl groups to the 9-position of the fluorene moiety does not interrupt the conjugation of internodal luminophore moieties, and there is also no aggregation or excimer emission both for functionalized and nonfunctionalized macromolecules in solution.
