Green light iridium (III) complex and a method of preparing the same

Abstract

The present invention provides a green light iridium (III) complex and a method of preparing the same, which has a formula as follows: wherein m is 2 or 3; at least one of Ar1, Ar2, Ar3, Ar4, and Ar5 is a group containing fluorophenyl unit, which has a formula as follows: wherein R1, R2, R3, R4, R5 are H, CH3, or FCF3, and at least one of R1, R2, R3, R4, R5 is F or CF3. The green light iridium (III) complex of the present invention has higher light emitting efficiency; the method of preparing the same has tender reaction conditions, simple synthesis steps and easy to handle. Due to the fluorophenyl unit capable of transporting electrons introduced therein, carrier current mobility and exciton transporting equilibrium are increased to contribute better exciton recombination so as to enhance performance of an organic electroluminescent device.
