NMR study on iridium(III) complexes for identifying disulfonate substituted bathophenanthroline regio-isomers.

Abstract

A series of novel biscyclometalated iridium (III) complexes with an ancillary disulfonated bathophenanthroline (DSBP(2-)) ligand, Ir(L)(2)DSBPNa, L = 2-phenylpyridine (ppy), 2,4-difluorophenylpyridine (fppy), and 1-phenylisoquinoline (piq) were found to have two isomeric forms. The chemical structures of the isomers were determined by the one- and two-dimensional (1)H and (13)C NMR studies. The isomeric state was proved to have originated from the disulfonate-related regio-isomer of the DSBP(2-) ligand.
