Tuning emission wavelength and redox properties through position of the substituent in iridium(iii) cyclometallated complexes†
Abstract
Cyclometallated phenyls with substituents para to the metal have a larger impact on the redox potentials and emission of complexes [Ir(R-ppz)2(bipy)][PF6] than substituents at the meta position and hence enable tuning of emission wavelength over a wider range using the same substituent.
