    1. Rhenium His-Tag Complexes

      Reactions of [Re(CO)3]+ with Histidylhistidine and Modified Histidines (pages 3905–3908)

      Richard S. Herrick, Christopher J. Ziegler and Americo Gambella

      Version of Record online: 20 JUL 2010 | DOI: 10.1002/ejic.201000532

      Reactions of His-tag models with [Re(CO)3(H2O)3]Br produce two compounds that display an unusual mode of binding. X-ray crystallography verifies that Ac-His-OH and His-His-OH (see figure) each produce a compound that has a peptide carboxamido-N donor group. Challenge experiments show that the complex with His-His-OH resists decomposition suggesting practical applications of complexed His-tags.

    2. Chiral Luminescent Complexes

      Heterochiral vs. Homochiral Linkage of Emissive Iridium(III) Complexes with D-Penicillaminate: Drastic Change in Emission Induced by Silver(I) Linkage (pages 3909–3913)

      Keisuke Saito, Yuta Sarukawa, Kiyoshi Tsuge and Takumi Konno

      Version of Record online: 16 JUL 2010 | DOI: 10.1002/ejic.201000689

      Emissive IrIII complexes [Ir(D-Hpen)(ppy or ppy-CF3)2] were converted into IrIIIAgIIrIII complexes by linking with AgI, which led to a drastic blueshift of the emission bands. Whereas the (ppy)IrIIIAgIIrIII complex produced only the ΔDΛD isomer, the ppy-CF3 complex gave the ΔDΔD andΛDΛD isomers that could completely be separated by crystallization. The emission quantum efficiencies for the ΔDΔD and ΛDΛD isomers were found to be markedly different, indicative of the importance of chirality in the control of emission properties.
