Abstract

Two series of (dfppy)2Ir(LN^O) with different substituents were designed and successfully synthesized and the effect of substitution at the ancillary ligand on the photophysical and electrochemical properties of (dfppy)2Ir(LN^O) were investigated. The results indicate that the electron-donating group of –OMe at LN^O increases the PL quantum efficiencies of (dfppy)2Ir(LN^O) and the electron-withdrawing groups of –CF3 and –F lower the PL quantum efficiencies.
