Three novel molecules were designed and synthesized based on a known compound 9,10-di(naphthalen-2-yl)anthracene (MADN). To broaden the π-conjugated system, three units with different electronegativity were introduced and connected to the C-2 position of MADN by vinyl unit. The Suzuki reaction, the Wittig reaction, and the Heck reaction were employed to synthesize these compounds. MADN is a well-known anthracene derivative which has been widely used as blue emitter. All these results indicate that these novel MADN derivatives could be some kind of potential materials for OLEDs.

新型9,10-二（萘-2-基）蒽衍生物的合成与性能

基于已知的化合物9,10-二（萘-2-基）蒽（MADN）设计并合成了三种新型分子。为了拓宽π共轭体系，引入了三个具有不同电负性的单元，并通过乙烯基单元将其连接到MADN的C-2位。使用Suzuki反应，Wittig反应和Heck反应合成这些化合物。MADN是一种众所周知的蒽衍生物，已被广泛用作蓝色发光体。所有这些结果表明，这些新颖的MADN衍生物可能是OLED的某种潜在材料。
