Hexanuclear Cylinder-Shaped Assemblies of Silver and Gold from Benzene–Hexa-N-heterocyclic Carbenes
摘要:
In this work we describe the preparation of a new benzenehexaimidazolylidene ligand, which we have coordinated to silver and gold. The new complexes constitute unique examples of cylinder-like macromolecular arrangements, in which six metal atoms are sandwiched between two hexacarbene ligands.

stabilities of the eight possible conformers of (imz) 6 bz and (mimz) 6 bz have been estimated by semi-empirical calculations at the AM1 level. In both compounds, the absolute minimum corresponds to the conformation in which the β nitrogen lone pair of consecutive imidazole rings is alternately oriented to opposite sides of the benzene plane. While in (imz) 6 bz only the ring signals corresponding to a unique

A transparent electrode is configured which is provided with: a nitrogen-containing layer; a conductive layer which is provided abutting the nitrogen-containing layer, and which has silver as a main component thereof; a high refractive index layer having a refractive index higher than that of the nitrogen-containing layer; and a low refractive index layer having a refractive index lower than that of the high refractive index layer. In the nitrogen-containing layer, a compound is used which includes nitrogen atoms, and which has, in cases when n represents the number of unshared electron pairs which are not involved in aromaticity and which are not coordinated to metal, from among the unshared electron pairs of the nitrogen atoms, and M represents molecular weight, an effective unshared-electron-pair content [n/M] that satisfies 2.0×10
