摘要： 合成了以β-二酮配体3-甲基-1-苯基-4-(十八烷基酰基)吡唑啉酮-5(PMOP)修饰的Al2O3纳米粒子,并用IR、UV光谱、NMR和荧光光谱等手段进行了表征.修饰后的Al2O3纳米粒子能溶于氯仿、乙醇和甲苯等常见有机溶剂,并有较强的蓝色荧光.表明在一些无机纳米粒子的表面键合上有机配体后,可以产生新的光物理性质.修饰后的Al2O3纳米粒子还可作为支架材料用于准固态染料敏化纳米晶太阳能电池中.

Abstract: A novel β-diketone ligand 3-methyl-phenyl-4-octadecyl-5-pyrazolone(PMOP) and nanoparticle Al2O3 modified by the ligand PMOP were synthesized and characterized by infrared spectroscopy, UV-Vis spectroscopy, 1H NMR and photoluminescence spectroscopy. The modified nanoparticle Al2O3 with good photoluminescence property can dissolve in the organic solvent such as chloroform, ethanol, and toluene and so on, which indicates that inorganic nanoparticle modified by organic ligand can show some new photophysical properties. Moreover, the modified nanoparticle Al2O3 can be used as a sustain material and applied to dye sensitized nanocrystal solar cell.

Key words: Nanoparticle Al2O3, Organic ligand modification, Dye sensitized solar cell
