Abstract Three zinc (II) complexes were synthesized from O,N,O-tridentate ligands with a charged side chain and a different electron withdrawing substituent. Metallated polymers with emission color tuning based on the same ligands moved interest. In the present study we collected information on the coordination environment and on the photoluminescence performance of the related model complexes. In pyridine solution RGB (red-greenblue) emission was achieved by lowering the withdrawing strength of the substituent. Two of the ligands were characterized by single crystal X-ray diffraction analysis that revealed the keto form and the shape adopted as uncoordinated molecules.

三种带电 O,N,O-螯合锌 (II) 配合物在吡啶溶液中的 RGB 发射

摘要 由具有带电侧链和不同吸电子取代基的 O,N,O-三齿配体合成了三种锌 (II) 配合物。基于相同配体的具有发射颜色调节的金属化聚合物引起了人们的兴趣。在本研究中，我们收集了有关协调环境和相关模型复合物的光致发光性能的信息。在吡啶溶液中，RGB（红绿蓝）发射是通过降低取代基的撤回强度来实现的。其中两个配体通过单晶 X 射线衍射分析表征，揭示了酮形式和采用的未配位分子的形状。
