摘 要: 合成2-苯基咪唑并[5, 6-f]鄰菲咯啉(PIP),2-(4-苯酚)咪唑并[5, 6-f]鄰菲咯啉(pHPIP),2-(4-甲氧基苯基)咪唑并[5, 6-f]鄰菲咯啉(pMPIP)和2-(4-甲酰基苯基)咪唑并[5, 6-f]鄰菲咯啉(pAPIP)等4種鄰菲咯啉衍生物,并分別以其為第一配體,選擇丁酸(BAH),正庚酸(HAH)和十四酸(TAH)為第二配體合成12種新的銪-鄰菲咯啉衍生物-脂肪酸熒光配合物。通過EDTA配位滴定分析、元素分析、紅外光譜、紫外可見光譜和熱分析對配合物的組成、結構進行表征,并研究其熱穩(wěn)定性能;采用熒光光譜分析研究其發(fā)光性能。結果表明,目標配合物比其對應的二元配合物的熒光強度大大提高,說明第二配體脂肪酸和第一配體之間產生很好的協同效應;該類配合物有較好的熱穩(wěn)定性,可成為很好的光致發(fā)紅光和電致發(fā)紅光材料。

Abstract:Four phenanthroline derivatives of 2-phenyl-imazole [5, 6-f]-(1, 10) phenanthroline, 2-(4-hydroxy-phenyl)- imazole [5, 6-f]-(1, 10) phenanthroline, 2-(4-methoxyl-phenyl)-imazole [5, 6-f]-(1, 10) phenanthroline and 2-(4-formacyl -phenyl)-imazole [5, 6-f]-(1, 10) phenanthroline were synthesized, and twelve new complexes of europium were then synthesized with these phenanthroline derivatives as the first ligand and butyric acid, n-heptanoic acid and tetradecanoic acid as the second ligand. The structure and composition of the title complexes were characterized by means of EDTA titrimetric method, elemental analysis, FT-IR and UV spectra analysis. Their thermal and luminescent properties were also investigated with thermal analysis and fluorescence spectra instruments, respectively. The results show that the luminescence intensity of the title complexes greatly increases in comparison with that of their corresponding binary complexes, this reveals the second ligands form very good synergistic effect with the first ligands. The title complexes possess excellent thermal stability properties, and are hopefully developed into fine PL and EL red materials.
