THE SYNTHESIS AND CHARACTERIZATION OF POLY(N-[5-(8-HYDROXYQUINOLINE)METHYL]ANILINE)/MESOSTRUCTURED V_2O_5 HYBRID MATERIALS

采用原位插层聚合法制备出层状有序的聚N-[5-(8-羟基喹啉)甲基]苯胺/介孔五氧化二钒(PNQA/Meso-V2O5)杂化材料.结果显示,PNQA插入后,Meso-V2O5的层间距由2.4nm增加到2.81nm,得到的杂化材料仍保持良好的层状结构.杂化材料的室温电导率比Meso-V2O5高出3个数量级.荧光分析表明,在乙醇介质中杂化材料的发射谱带与PNQA相比蓝移22nm,杂化材料的荧光量子产率(26%)明显高于PNQA(10%).

Poly （ N- [ 5-（8-hydroxyquinoline） methyl ] aniline）/Meso-V2O5 （ PNQA/Meso-V2O5 ） hybrid materials were synthesized by intercalative polymerization method. The results show that the interlayer spacing of the Meso-V2O5 has increased from 2.40 nm to 2.81 nm, while the lamellar of V2O5 is preserved. The electrical conductivity of the hybrid materials is by 3 orders of magnitude higher than that of the Meso-V2O5. The photoluminescence analysis indicates that the emission band of the hybrid is blue shifted 22 nm in comparison with that of pure PNQA, and the hybrid gives a quantum yield of 26% ,which is higher than that （10%） of PNQA in ethanol.
