Reversible formation and dispersion of chiral assemblies responding to electron transfer
Electron -transfer reduction of p -benzoquinone (Q) and 1,4-n a phthoqu i none (NQ), in the presence of [R -(R ,R)]-2,6-bis(4,5-dihydro-4-phenyl-2-oxazolinyl)pyridine [SC3+(R )-pybox] results in formation of chiral pi-radical anion dimer complexes [(Q center dot (-))(2)-(Sc-3 (+)(R )-pybox)(2) and (NQ center dot(-))(2) -(Sc3+(R )-pybox)(2), respectively].
