Rapid and selective detection of nitroaromatic explosives is very important for public safety, life, and environmental health. Current instrumental techniques suffer from high cost and poor site used. In order to investigate fluorescence sensing of nitroaromatics, we prepare a new small fluorescence probe derived from pamoic acid. This study covers the synthesis of Pamoic acid based [diisopropyl 4,4'-methylenebis(3-methoxy-2-naphthoate)] (2) material and characterization of its structure. The methylation of Pamoic acid ester, which we have successfully synthesized in our previous studies, was carried out in this study. Determination of the photophysical and fluorescent nitroaromatic detection properties of the compound forms the basis of the study. Structural characterization of the synthesized compound [diisopropyl 4,4'-methylenebis(3-methoxy-2-naphthoate)] (2) was characterized using spectroscopic methods. In addition, Molecular structure of the synthesized compound was determined by single crystal X-ray diffraction studies. In the final step, compounds [diisopropyl 4,4'-methylenebis(3-hydroxy-2-naphthoate)] (1) and [diisopropyl 4,4'-methylenebis(3-methoxy-2-naphthoate)] (2) were tested as fluorescent probes for the detection of some nitroaromatic explosives. It is seen that Nitrobenzene provides the best quenching effect on the compound [diisopropyl 4,4'-methylenebis(3-hydroxy-2-naphthoate)] (1) containing the -OH group, with lowest the limit of detection (LOD) value. It was observed that Picric acid provided the best quenching effect with lowest the limit of detection (LOD) value in the compound [diisopropyl 4,4'-methylenebis(3-methoxy-2-naphthoate)] (2) obtained by methylation of the -OH group in the compound [diisopropyl 4,4'-methylenebis(3-hydroxy-2-naphthoate)] (1).

硝基芳烃爆炸物的快速选择性检测对于公共安全、生命和环境健康具有重要意义。当前的仪器技术存在成本高和使用场地差的问题。为了研究硝基芳烃的荧光传感，我们制备了一种新型的源自双羟萘酸的小型荧光探针。本研究涵盖基于双羟萘酸 [diisopropyl 4,4'-methylenebis(3-methoxy-2-naphthoate)] ( 2) 材料及其结构的表征。我们在之前的研究中成功合成的 Pamoic 酸酯的甲基化在本研究中进行。该化合物的光物理和荧光硝基芳烃检测特性的确定构成了研究的基础。合成化合物 [diisopropyl 4,4'-methylenebis(3-methoxy-2-naphthoate)] ( 2 ) 的结构表征使用光谱方法进行了表征。此外，通过单晶 X 射线衍射研究确定了合成化合物的分子结构。在最后一步中，化合物 [diisopropyl 4,4'-methylenebis(3-hydroxy-2-naphthoate)] ( 1 ) 和 [diisopropyl 4,4'-methylenebis(3-methoxy-2-naphthoate)] ( 2) 作为检测某些硝基芳族爆炸物的荧光探针进行了测试。可见，硝基苯对含有-OH基团的化合物[diisopropyl 4,4'-methylenebis(3-hydroxy-2-naphthoate)] ( 1 )的猝灭效果最好，检测限(LOD)值最低. 据观察，苦味酸在化合物 [diisopropyl 4,4'-methylenebis(3-methoxy-2-naphthoate)] ( 2 )中的检测限 (LOD) 值最低时提供了最好的淬灭效果。化合物[4,4'-亚甲基双(3-羟基-2-萘甲酸)二异丙酯]( 1 )中的-OH基团。
