摘要
设计合成了3种新型含单氟8-羟基喹啉衍生物配体:(E)-2-[2-(2-氟代苯基)乙烯基]-8-羟基喹啉(4a)、(E)-2-[2-(3-氟代苯基)乙烯基]-8-羟基喹啉(4b)、(E)-2-[2-(4-氟代苯基)乙烯基]-8-羟基喹啉(4c)及其相应的锌配合物(5a)、(5b)、(5c),利用1 H-NMR、IR、MS、元素分析确认了其结构。测定了它们在DMF溶液中的荧光性质;荧光光谱显示化合物4a、4b、4c在DMF溶液中的λmax分别是505nm、487nm、513nm;5a、5b、5c的λmax分别是559nm、598nm、588nm,荧光光谱显示氟基位置的改变可以调控8-羟基喹啉锌配合物的发光性质。
In order to explore high performance of organic electroluminescent （EL） materials, three new 8- hydroxyquinoline derivatives and their zinc complexes have been designed, synthesized and identified by HNMR, IR, MS spectra and elemental analyses. The luminescence properties of the compounds.. （5a）, （5b） and （5c） were investigated by fluorescence spectra in DMF at room temperature. The results showed that theλmax of compounds .. 4a, 4b and 4c were 505nm, 487 nm and 513 nm in DMF solution. 5a, 5b and 5c were 559 nm, 598 nm and 588nm, respectively. The comparative study of the luminescent properties of 5a, 5b and 5c showed that the emission λmax can be tuned by introducing fluorine groups at different positions.
