Metalla-Supramolecular Rectangles as Electron Reservoirs for Multielectron Reduction and Oxidation.

Original language description

The electron-transfer capacity of molecular rectangle ions [Pt-4(II)(PEt3)(8)(mu-anth(2-))(2)(mu-L)(2)](4+) with anth = anthracene-1,8-diyl and L = 4,4''-bipyridine (bp) or 1,2-bis(4-pyridyl)ethene (bpe) was investigated in acetonitrile and dichloromethane using cyclic voltammetry, EPR, and UV-vis-near-IR spectroelectrochemistry. The compounds can be reversibly reduced, first in a two-electron process and then via two closely separated one-electron steps. Oxidation was also possible at rather low potentials in a reversible two-electron step, followed by an electrochemically irreversible process. The spectroscopic results indicate reduction at the neutral acceptor ligands L and oxidation at the formally dianionic anthracene 'clips'. In contrast, the prototypical molecular square {[Pt(triphos)(mu-bp)](4)}(8+) undergoes only irreversible reduction.
