 Highly electron-rich triarylamines, which are known to have high hole mobility, have been widely used as hole-transporting materials in multilayer organic electro-luminescence devices.5 However, triphenylamine (TPA) derivatives have the tendency to crystallize upon exposure to heat resulting in aggregation-induced fluorescence quenching of fluorophores, and often possess low glass transition temperatures (Tg)(i.e., poor morphological stability), resulting in low reliability when used in optoelectronic devices. Aggregation quenching and lowTg are the major reasons for the rare use of TPA derivatives for layer emission in electroluminescent device applications. Conse-quently, many structural modifications have been made in attempts to develop new TPA derivatives that possess high morphological stability and optoelectronic properties.6 On the other hand, we have already reported in the recent works a new class of triphenylethylene carbazole derivatives that displayedstrong blue light emissions, high Tg temperatures and AIE effects.7 We are thus extending these studies by combining dicarbazolyl triphenylethylene and triarylamine units into a single compoundvia synthetic methodology, and to design materials with potential technological applications. |
