Abstract
In this thesis, we synthesized a series of ferrocene-based triphenyl amine compounds via different approaches. By using electrochemical method and spectral electrochemistry we could observe their properties and then make into devices.
First, the research was divided into two sections: (1) Using OXD as the connecting group. (2) Using C=C as the connecting group. We have further composed PLED devices about applying electropolymerization of these kinds of compounds as hole transporting layer on ITO glass.
In the meanwhile, we also found that compounds being connected by OXD rings, electronic coupling between the ferrocene and triphenyl amine could be prevented by using OXD ring as connecting unit. It could also use the electronic withdrawing ability properties to moderate the ferrocene’s oxidative potential. When we tune different oxidative units’ potentials of the ferrocene and triphenyl amine at the same, this electopolymerized film would have better hole transporting efficiency and could be made into high performance light emitting device. The device has 27700 cd/m2 of brightness and efficiency of 14.3 cd/A. Its performance is almost as good as PEDOT.
