A New Electron-Transfer Donor for Photoinduced Electron Transfer in Polypyridyl Molecular Assemblies

A New Electron-Transfer Donor for Photoinduced Electron Transfer in Polypyridyl Molecular Assemblies

A synthetic procedure has been devised for the preparation of the reductive quencher ligand 4-methyl-4‘-(N-methyl-p-tolylaminomethyl)-2,2‘-bipyridine (dmb-tol), which contains toluidine covalently bound to 2,2‘-bipyridine. When bound to ReI in [ReI(dmb-tol)(CO)3Cl], laser flash ReI → dmb metal-to-li...

Zusammenfassung:A synthetic procedure has been devised for the preparation of the reductive quencher ligand 4-methyl-4‘-(N-methyl-p-tolylaminomethyl)-2,2‘-bipyridine (dmb-tol), which contains toluidine covalently bound to 2,2‘-bipyridine. When bound to ReI in [ReI(dmb-tol)(CO)3Cl], laser flash ReI → dmb metal-to-ligand charge-transfer (MLCT) excitation at 355 nm in CH3CN at 298 ± 2 K is followed by efficient, rapid ( 4 × 108 s-1 at 298 ± 2 K.
