In this work, two novel mixed-ligand CPs that has a compositions of [Co(µ-Hdppa)(phen)(HO)] (1) and {[Co(µ-Hdppa)(µ-4,4'-bipy)(HO)]·HO} (2) is achieved through reaction of cobalt salts with the 5-(3,4-Dicarboxylphenyl)picolinic acid (Hdppa) with various N-donor co-ligands (1,10-phenanthroline (phen) for 1 and 4,4'-bipyridine (4,4'-bipy) for 2). The structures and characteristics of these two complexes were fully examined via IR, TGA, and SXRD. Furthermore, their superior blue fluorescence properties compared to the original ligands were confirmed through fluorescence spectroscopy. These two complexes prepared in this study have enriched the choices for blue fluorescent materials.
在本工作中,通过钴盐与5-(3,4-二羧基苯基)吡啶甲酸(Hdppa)与各种含氮供体共配体(1中为1,10-菲咯啉(phen),2中为4,4'-联吡啶(4,4'-bipy))反应,得到了两种新型混合配体配合物,其组成为[Co(µ-Hdppa)(phen)(H₂O)] (1)和{[Co(µ-Hdppa)(µ-4,4'-bipy)(H₂O)]·H₂O} (2)。通过红外光谱(IR)、热重分析(TGA)和单晶X射线衍射(SXRD)对这两种配合物的结构和特性进行了全面研究。此外,通过荧光光谱证实了它们与原始配体相比具有优异的蓝色荧光特性。本研究制备的这两种配合物丰富了蓝色荧光材料的选择。
