具有复合性能的新型三脚架型多苯并咪唑季铵盐类化合物的合成、表征和应用

合成了15种新型三脚架结构苯并咪唑季铵盐类化合物(3a~3o)。 通过IR、NMR和HRMS等技术手段对目标产物(3a~3o)进行了结构表征。 并对目标化合物调节植物生长活性进行了评价。 结果表明, 目标化合物浓度为10 mg/L时, 化合物3a、3c、3f、3g、3h、3i和3j均具有优良的促细胞分裂活性, 最高达88.3%, 比参照物三唑酮(50.2%)的促细胞分裂活性更高, 但生长素活性不明显;目标化合物均具有优异的除草活性, 其中化合物3i效果最明显, 可以达到95.6%。 同时利用荧光光谱, 探究了4种代表性目标分子对人体中常见的6种阴离子的荧光识别, 结果发现目标化合物能较好的识别I^- , 可作为I^-荧光识别探针。

Synthesis and Application of Novel Tripod-type Benzimidazolium Compounds

Fifteen new tripod type benzimidazolium salts(3a~3o) were synthesized and characterized by IR, NMR and HRMS. The plant growth regulating activities of compound 3 were evaluated. Compounds 3a, 3c, 3f, 3g, 3h, 3i and 3j exhibit excellent cytokinesis activities up to 88.3% at the concentration of 10 mg/L which are higher than that of the reference triadimefon(50.2%), but their auxin activities are not obviously effective. Nearly all the target compounds have excellent herbicidal activity, while compound 3i is the best with 95.6%. The fluorescent identification of the four representative target molecules on six important anions was explored by fluorescence spectrum. The target compounds can be used as fluorescence probe for I^- identification.
