terpyridines those obtained as solids exhibited high thermal stability as opposed to those which were oils (tpy containing fluorene motif). Due to the fact that high thermal stability of 4'-phenyl-2,2':6′,2″-terpyridine derivatives showed photoluminescence (PL) quantum yield (Φ) in the range of 27–84% in solution, their electroluminescence ability was tested in diodes with guest-host configuration. For the compounds
4'-苯基-2,2':6',2''-吡啶(tpy)与乙炔基(T1),2-乙炔基-9,9-二辛基芴(T2),9,9-二辛基芴(T3)的新型衍生物分别通过Sonogashira或Suzuki-Miyaura偶联反应获得9-乙炔基-10-癸氧基蒽(T4)取代基,并进行了全面表征。乙炔基桥的存在通过将吸收光谱和发射光谱移向与T3相比更长的波长来影响新型化合物的光物理性质,其中芴通过单键与tpy连接。TGA测量表明,在新的三联吡啶中,以固体形式获得的那些与油(具有芴基的tpy)相反,表现出高的热稳定性。由于4'-苯基-2,2':6',2''-吡啶吡啶衍生物的高热稳定性显示出溶液中的光致发光(PL)量子产率(Φ)在27-84%的范围内,它们的电致发光该功能已在带有来宾-主机配置的二极管中进行了测试。对于分散在由聚(9-乙烯基咔唑)(PVK)(50 wt%)和(2-叔丁基)组成的基质中的化合物观察到最大波长在374至531
