| 摘 要： | 以4′-(2-苯并噻唑基)苯并-9-冠-3(BTZ9C3)为主配体,用2,2′-联吡啶(bpy)及3-三氟甲基-5-(2′-吡啶基)-1,2-二唑(Hfppz)辅助配体分别合成了离子型铱配合物Ir(BTZ9C3)2(bpy)]PF6(1)和中性铱配合物Ir(BTZ9C3)2(fppz)](2)。配合物的结构通过核磁、高分辨质谱进行了表征,并测定了配合物1的单晶结构。对它们光物理性能的研究表明,2种配合物掺杂在PMMA中的发光为黄绿光发射,配合物1的发光波长为535 nm,配合物2的发光波长为541 nm,发光量子效率分别为10.8%,45.0%,发光寿命分别为3.01和2.58μs,为典型的磷光发射。通过循环伏安法测得配合物1和2的HOMO能级分别为-5.60和-5.35 eV。2种配合物对Be2+都有发光增强的选择性识别效果,化学计量比为1∶2,最低检测限低至6.0μmol·L-1。抗干扰能力方面,离子型配合物1的抗干扰能力较好,而中性配合物2受Al3+的干扰较大。
