摘要：

In this paper, two new TPE-based conjugated molecules, constructed using tetraphenylethene (TPE) and carbazole or spirofluorene moieties, have been successfully prepared. They exhibited aggregation induced emission (AIE) properties, high thermal and morphological stabilities, and low oxidation potential, making them promising properties for optoelectric materials. The fabricated non-doped multilayer OLEDs demonstrate that devices using these luminophors as the emitting layer show relatively good performance, and the device of SFTPE gives a maximum luminance and efficiency of 8196 cd m(-2) and 3.33 cd A(-1), respectively, with the maximum emission wavelength at about 466 nm, thanks to the adjusted molecular structure and AIE characteristic of TPE.
