合成了一系列具有发光功能的非共轭聚氨酯衍生物。该聚合物显示出对2，4，6-三硝基苯酚（TNP）（苦味酸）的高选择性和灵敏度检测。对TNP的选择性是通过强内过滤效应（IFE）、福斯特共振能量转移（FRET）和光诱导电子转移（PET）的组合来实现的。通过将聚合物PU 1固定在滤纸上，构建了一种方便的TNP目视检测试纸。PU-1涂层滤纸可快速检测水中的TNP，浓度下限为10（-10）M，约为0.229 ag cm（-2）。这是一种简单、低成本、高效率的TNP检测方法。
A series of luminescent non-conjugated polyurethane derivatives (PUs) has been obtained in a facile way in high yields. The polymers show highly selective and sensitive detection of 2,4,6-trinitrophenol (TNP) (picric acid). The selectivity for TNP is accomplished via combination of a strong inner filter effect (IFE), Forster resonance energy transfer (FRET) and photoinduced electron transfer (PET). A convenient indicator paper for the visual detection of TNP has been constructed by immobilization of the polymer PU1 on filter paper. The PU1-coated filter paper presents a rapid detection of TNP in water with a low concentration limit of 10(-10) M, approximate to 0.229 ag cm(-2). This is a simple, low-cost and highly efficient method for the detection of TNP.
