摘要：
Treatment of difluorobenzyldiphenylphosphine with the Ir(III) dimer [(dfppy)(2)Ir(mu-Cl)](2) gives (N, N)-trans-[Ir(dfppy)(2)-(dfbdpH)Cl], followed by skeletal isomerization to form its (N, N)-cis analogue, and then the fully cyclometalated complex [Ir(dfppy)(2)(dfbdp)]; the last complex and its derivative are suitable for fabrication of true-blue phosphorescent OLEDs.
