The energy relay dye, 4-(Dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM), was used with a near-infrared sensitizing dye, TT1, to increase the overall power conversion efficiency of a dye-sensitized solar cell (DSC) from 3.5% to 4.5%. Th ...

High-efficiency flexible dye-sensitized solar cells were fabricated with a Ti-metal foil substrate for photo anode and using a Pt-electrodeposited counter electrode on ITO/polyethylene naphthalate (ITO/PEN); these devices were characterized by incident pho ...

A compound, in metal-free or metal complex form of formula (1) to (3) in which R is hydrogen or C1-30 alkyl; X is hydrogen, halogen (preferably Cl or Br) or C1-30 alkyl. ...

The "naked sugar" (+)-(1R,2S,4R)-2-cyano-7-oxa-bicyclo[2.2.1]hept-5-en-2-yl (1S)-camphanate [(+)-3] (Diels-Alder adduct of furan with 1-cyanovinyl (1S)-camphanate) was converted into (1R)-1-C-(6-amino-7H-purin-8-yl)-1,4-anhydro-2,3-dideoxy-3-fluoro-D-eryt hro-pentitol [(+)-2] in nine synthetic steps and 12% overall yield.
