摘要/Abstract

摘要： 易制爆类硝基化合物的检测是环境污染控制及公共安全领域的研究热点。以高荧光量子效率的发光铂配合物[Pt(ppy)(CH3CN)2]ClO4作为荧光探针，检测硝基化合物4⁃硝基甲苯(4⁃NT)。[Pt(ppy)(CH3CN)2]ClO4的荧光发射强度随着4⁃NT的加入而逐渐降低直至淬灭，利用Stern⁃Volmer方程拟合实验数据，得到[Pt(ppy)(CH3CN)2]ClO4对4⁃NT的检测效率KSV为40.2 L/mmol，最低检测限为1.83×10-6 mol/L。通过光谱实验及DFT计算证实，[Pt(ppy)(CH3CN)2]ClO4对4⁃NT的检测机理为能量传递机理及电子转移机理的协同作用。

Abstract: The detection of explosive nitro compounds is a key research topic in the field of environmental pollution control and public safety. The luminescent platinum complexes [Pt(ppy)(CH3CN)2]ClO4 with high fluorescence quantum efficiency was applied as fluorescent probe to detect nitrocompound 4⁃nitrotoluene (4⁃NT). The fluorescence emission intensity of [Pt(ppy)(CH3CN)2]ClO4 decreased gradually until quenching with the addition of 4⁃NT. The detection efficiency KSV of 40.2 L/mmol was obtained by fitting experimental data with Stern⁃Volmer equation, and the minimum limit of detection was 1.83×10-6 mol/L. It is confirmed by spectrum experiment and DFT calculation that the detection mechanism of 4⁃NT by [Pt(ppy)(CH3CN)2]ClO4 was investigated to be synergistic effect of energy transfer and electron transfer.
