摘要
以2-苯基吡啶(ppy)为主配体,4-(3,6-二叔丁基-9H-咔唑-9-基)-N-(4-(3,6-二叔丁基-9H-咔唑-9-基)苯基)-N-(4-(5-(吡啶-2-基)-1,3,4-噁二唑-2-基)苯基)苯胺(CPPOA)为辅助配体,合成了一种树形阳离子型铱(Ⅲ)配合物[(ppy)2Ir(CPPOA)]PF_(6)。该配合物具有较高的聚集诱导发光(AIE)活性,将其溶于CH_(3)CN/H_(2)O混合溶剂中(浓度1.0×10^(-5)mol/L),在溶剂含水量f_(w)≥50%时呈现橙红色光致发光,且强度随f_(w)增大而不断增强,量子产率相应地从2.6%(f_(w)=50%)增长至50.7%(f_(w)=90%),固体粉末态时为54.7%。采用简便的扫尘法,可将该配合物成功用于潜指纹的可视化和检测,一、二、三级指纹细节均清晰可辨。
Using 2-phenylpyridine(ppy)as main ligand and 4-(3,6-di-tert-butyl-9H-carbazol-9-yl)-N-(4-(3,6-di-tert-butyl-9H-carbazol-9-yl)phenyl)-N-(4-(5-(pyridin-2-yl)-1,3,4-oxadiazol-2-yl)phenyl)aniline(CPPOA)as auxiliary ligand,a dendri⁃meric cationic iridium(Ⅲ)complex[(ppy)2Ir(CPPOA)]PF6 was synthesized.The complex showed high aggregation-induced emission(AIE)activity.The solutions of the complex in mixed solvents of CH_(3)CN/H_(2)O(1.0×10^(-5)mol/L)emitted orange-red light via photoluminescence(PL)when f_(w)≥50%(f_(w):water fraction),and the PL intensities enhanced with the increasing of f_(w).Moreover,the quantum yields correspondingly increased from 2.6%(f_(w)=50%)to 50.7%(f_(w)=90%),and further increased to 54.7%in solid powders.It was successfully used for visualizing and detecting latent fingerprints via a simple powder dusting method,resultantly,the first,second,and third level fingerprint details all were clear and distinguishable.
