合成了三种1,10-邻菲罗啉苯并咪唑衍生物,即2-苯基(4-溴)-咪唑[4,5-f][1,10]-邻菲罗啉(A1),2-苯基(4-甲氧基)-咪唑[4,5-f][1,10]-邻菲罗啉(A2)和2-苯基(4-甲基)-咪唑[4,5-f][1,10]-邻菲罗啉(A3)。通过核磁和红外进行了结构表征,并开展了光物理和化学特性测试。以m-MTDATA为给体,1,10-邻菲罗啉衍生物为受体制备了有机紫外光探测器件。在光强为1.2mW/cm2的365nm紫外光照射下,基于器件结构为ITO/m-MTDATA/m-MTDATA∶A3/A3/LiF/Al的优化器件在-10V时的最大光电流密度为89μA/cm2。根据材料性质和器件结构讨论了器件性能的变化。
Three kinds of 1,10-phenanthroline benzimidazole derivatives were synthesized, that is, 2-phenyl (4-bromo) -imidazo [4,5-f] [1,10] 2-phenyl (4-methoxy) -imidazo [4,5-f] [1,10] 5-f] [1,10] -phenophenanthroline (A3). Structural characterization was carried out by NMR and IR, and photophysical and chemical properties tests were carried out. Using m-MTDATA as donor and 1,10-phenanthroline derivative as acceptor, organic UV detector was prepared. The optimized device based on device structure of ITO / m-MTDATA / m-MTDATA: A3 / A3 / LiF / Al under the irradiation of 365nm ultraviolet light with a light intensity of 1.2mW / cm2 has a maximum photocurrent density of 89μA / cm2. The device performance changes are discussed based on the material properties and device structure.
