Linking of N3 dye to another TiO2-attached N3 dye rendered an enhanced short-circuit photocurrent and thereby higher efficiency for the dye-sensitized solar cell with the pertinent TiO2film electrode.

Desymmetrization of the mesodienynes, such as propargyl 1-vinylallyl N-tosylamides 1a–c and propargyl 1-vinylallyl ethers 1d–e, by asymmetric Pauson–Khand type reaction catalysts was studied. The corresponding vinyl substituted bicyclic pentenones 2and 3 were obtained with high diastereoselectivity and enantioselectivity.
