Cyclometallated, bis-terdentate iridium complexes as linearly expandable cores for the construction of multimetallic assemblies
Cyclometallated iridium complexes comprised of two terdentate cyclometallating ligands, of the form [Ir(NCN)(NNC)]+, have been explored for the preparation of multimetallic systems by palladium-catalysed cross-coupling reactions. An NNC-coordinating ligand carrying a boronate ester group has been prepared and complexed to iridium to give a boronic acid appended complex of this type, 3. This complex has been subjected to cross-coupling with a bromo-substituted bis-terpyridyl iridium complex to give a dinuclear iridium compound 6, in which one of the two iridium centres is N6-coordinated and the other has an N4C2-coordination sphere. Meanwhile, a bromo-substituted complex 4 has been coupled with a boronic acid-appended ruthenium complex, to give a dinuclear heterometallic complex 8 that can be activated to a second coupling by in situ bromination, offering access to a linear Ir-Ir-Ru trimetallic assembly 11. The electrochemical and luminescence properties of these systems are investigated. In the case of 8 and 11, the behaviour can be rationalised in terms of a supramolecular description: efficient energy transfer occurs from the Ir terminus to the Ru. In contrast, for compound 6, an excited state with significant bridge character appears to play a key role in determining the emission properties. The Royal Society of Chemistry 2009.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 95464-05-4 is helpful to your research. Synthetic Route of 95464-05-4
