随着国家安全战略、环境保护意识的逐步提高,硝基芳香爆炸物苦味酸(PA)的高选择性和灵敏性检测受到格外的关注.为了适应绿色化学的潮流,无金属离子(尤其是重金属离子)外辅助荧光增强的,且易于制备与加工的纯有机分子荧光探针,在各种PA检测技术中更加受到重视.从分子设计与合成的角度,根据探针的分子组成,将无外辅助荧光增强的纯有机分子PA检测探针分为聚合物、齐聚物和小分子等三类,分别介绍了其研究进展,并展望了其未来的发展趋势.
With the national security strategy and the increasing awareness of environmental protection, special attention has been paid to the detection of the high selectivity and sensitivity of the nitryl aromatic explosives picric acid (PA) .In order to adapt to the trend of green chemistry, metal-free ions (especially heavy metals Ion) external auxiliary fluorescence enhanced, and easy preparation and processing of pure organic molecular fluorescent probe in a variety of PA detection techniques more attention from the molecular design and synthesis point of view, according to the molecular composition of the probe, there will be no Assisted fluorescence enhancement of pure organic molecules PA detection probe into polymer, oligomers and three kinds of small molecules, respectively, introduced its research progress, and prospects for its future trends.
