摘要
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。
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.
