Structure-property Relationship of Organic Electroluminescent Materials with Dimeric Quinoline Structure

： Three novel linear dimeric luminescent materials ， BtCzPPQ ， DCPPQ and PZPPQ ， were synthesized by linking two quinoline receptors together into an electron acceptor （ A ） using the Suzuki coupling reaction ， and by linking donor groups （ D ） with different electronic donated moiety. All the three materials have good rigidity ， thermal stability （ T g >220 ℃ ）， and high photoluminescence quantum yields （ PLQYs more than 70% ） . The effects of structur⁃ al factors such as the rigidity of molecules ， linear length ， and the donor group on the electroluminescence properties of the materials were analyzed by characterizing the orbital distribution ， thermal stability ， and photophysical proper⁃ ties of the materials.

期刊介绍： Chinese Journal of Luminescence (CJL), supervised by Chinese Academy of Sciences (CAS), Sponsored by Committee on luminescence of Chinese Physical Society and Changchun Institute of Optics, Fine mechanics and Physics（CIOMP）of Chinese Academy of Sciences, is an authoritatively scientific and technical periodical of China in the field of luminescence, which is read widely in providing original papers and reviews that describe recent developments on basic theory and experimental studies of excited state processes and green lighting projects. The journal was established at 1980, and named after LUMINESCENCE AND DISPLAY, then renamed as CJL in 1986.
