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%. The unattached DCM dyes exhibit an average excitation transfer efficiency (ETE) of 96% inside TT1-covered, mesostructured TiO(2) films. Further...

Electrospray ionisation mass spectrometry shows that arylstibonic acids, RSbO(3)H(2), give rise to oxo-bridged clusters derived from [H(8)(RSb)(12)O(28)] which act as inorganic crown ligands towards Na(+) cations; structure determination of one derivative revealed a cage-like anion [Na(2)H(9)(p-O(2)NC(6)H(4)Sb)(12)O(30).4H(2)O](-).
