Effective suppression of interfacial charge recombination by a 12-crown-4 substituent on a double-anchored organic sensitizer and rotating disk electrochemical evidence
palladium and rhodium catalysis. The catalytic activities correlated well with the extractabilities of the phosphine ligands. The compound [RhCl(cod)]2, combined with IIIc and IIId, shows high activities toward catalytic hydrogenation of potassium and caesium cinnamates, respectively. Replacement of allyl bromide with powdered sodium or potassium iodide in benzene to give allyl iodide are catalyzed by

A crown-ether-substituted double-anchored organic dye suppressed charge recombination with iodide and cobalt redox mediators to reach the efficiencies of 10.12% (under 1 sun) and 11.17% (under 0.1 sun).
Molecular Design of Crown Ethers. 19.<sup>1</sup> Synthesis of Novel Disulfide- and Diselenide-Bridged Bis(benzo-12-crown-4)s and Their Ag<sup>+</sup>-Selective Electrode Properties
Two novel heteroatom-bridged bis(benzo-12-crown-4 ether)s, i.e., bis(2-nitro-4,5-(1,4,7,10-tetraoxadecamethylene)phenyl) disulfide (4) and diselenide (5), have been synthesized and characterized by elemental analysis and mass, IR, UV, and (1)H NMR spectroscopy. An X-ray crystallographic structure was obtained for 4. Ion-selectiveelectrodes (ISE) for Ag(+), containing 4 and 5 in PVCmembrane as neutral
