Abstract:

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.
