| titleOfInvention | A novel AIE material based on seven-membered cyclic imide and its preparation method and method for preparing organic electroluminescent devices |
| abstract | The invention discloses a novel AIE material based on a seven-membered cyclic imide, a preparation method thereof, and a method for preparing an organic electroluminescence device. Based on these small acceptor molecules with active sites, a series of novel D‑A‑D luminescent materials with AIE characteristics were synthesized by introducing the donor through the coupling reaction of Suzuki et al. The present invention designs and synthesizes D-A-D biphenylimide/diimide with AIE characteristics for the first time, and its unique twisted structure exhibits unique optoelectronic properties and thermally activated delayed fluorescence properties. The preparation method of the imide compound of the invention is easy to operate and mild in reaction conditions; the prepared electroluminescent device has large external quantum efficiency and high brightness, and is a kind of organic electroluminescent small molecule material with excellent performance. object material. The invention not only makes up for the shortage of imide material structure types, but also broadens its application in organic electroluminescence devices. |
