中文摘要：

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/cm^2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/cm^2。根据材料性质和器件结构讨论了器件性能的变化。

英文摘要：

Three imidazo [4,5-f][1,10]-phenanthroline derivatives were synthesized and characterized by 1H NMR,FTIR,UV,PL and AFM.The OUV-PDs were fabricated with mMTDATA as donor and imidazo [4,5-f][1,10]-phenanthroline derivatives as acceptor.The structures of OUV-PDs were ITO/m-MTDATA/m-MTDATA∶A1or A2 or A3（1∶1）/A1 or A2or A3/LiF/Al.Under an illumination of 365 nm UV light with power of 1.2 mW/cm^2,the maximum value of photocurrent density was 50,69 and 89μA/cm^2,respectively. The performance of OUV-PDs was discussed based on the properties of the device materials and structure.
