苦味酸的灵敏和选择性检测对社会安全和人类健康至关重要。本文成功地合成了一种新型的含咔唑基团的蓝色铱(III)发光复合物FIrPicOMPBHCz,并将其应用于对硝基芳族炸药(如PA,TNB,DNP,TNT,DNT,NP,NBA,NB)的光致发光(PL)传感中。检测。FIrPicOMPBHCz的PL排放可以通过不同程度的炸药来猝灭。其中,对PA的淬灭常数K SV最高,为1.9×10 4 M -1,其比其他硝基芳族化合物高一到两个数量级,因此证明了对PA的选择性PL检测。感应机制基于激发态电子转移过程,通过分析UV-vis吸收,激发和PL光谱以及循环伏安图结果。此外,纸条测试表明FIrPicOMPBHCz作为PA的固态PL传感器具有巨大的潜力。

A new kind of peripheral carbazole substituted ruthenium(II) complexes [Ru(bpy)2(tkdp-bpy)(AsF6)2] (4) (bpy = bipyridine, tkdp-bpy = 4,4′-(3,5-bis(6-(9H-carbazol-9-yl)hexyloxy)phenyl)methoxycarbonyl-2,2′-bipyridine) and [Ru(bpy)2 (dkte-bpy)(ClO4)2] (5) (dkte-bpy = bis(4-(9H-carbazol-9-yl)butyl)-2,2′-bipyridine-4,4′-dicarboxylate) were synthesized and their photophysical, electrochemical, as well as electroluminescent (EL) properties were studied. They display intense deep red phosphorescent emission centered at 660 nm and 658 nm, respectively, both in solution and in the solid state at room temperature. The peripheral carbazole in the complexes acts as an electrochemical coupling unit providing the ability to carry out electrochemical deposition (ED) and to form an ED film on an ITO electrode under a positive potential. Highly luminescent ED films are obtained under a carefully controlled ED process, and used as emitting layers in organic light-emitting diodes (OLEDs). The diodes gives out strong pure red emission and a luminous efficiency of 3.9 cd/A. These are the first electropolymerized phosphorescent OLEDs to be reported.

The sensitive and selectivedetection of picricacid is of great importance to the society safety and human health. In this paper, a novel blue emissive iridium(III) complex FIrPicOMPBHCz containing carbazole moieties has been successfully synthesized and applied in photoluminescence (PL) sensing towards nitroaromatic explosives (e.g. PA, TNB, DNP, TNT, DNT, NP, NBA, NB) detection. The PL emission
