摘要 | 2-{12-Oxobenzo[b] acridin-5(12H)-yl} -acetic acid (BAAA) reacted with coupling agent N, N'-carbonyldiimidazole (CDI) to form an activated amide intermediate 5-[2-(1H-imidazol-1-yl)-2-oxoethyl] benzo[b]acridin-12(5H)-one(IEBA), which was a novel fluorescence probe. The amide intermediate(IEBA) reacted preferably with amines in DMF solvent in the absence of catalysts to give the high yields of derivatives, which not only have high fluorescence sensitivity but also have strong ionizable ability. The optimum excitation and emission wavelengths were at lambda(ex)/lambda(em) = 272 nm/505 nm. The percent ionization 8 values in aqueous acetonitrile and aqueous methanol were in the range of 0-57. 32% and 0-62. 14%, respectively. The fluorescence detection limits of twelve amine derivatives(at a signal-to-noise ratio of 3) were in the range of 0. 15-0. 50 ng/mL. The online APCI-MS detection limits were at levels of 1. 43-8. 51 ng/mL(S/N = 3).; 2-{12-Oxobenzo[b] acridin-5(12H)-yl} -acetic acid (BAAA) reacted with coupling agent N, N'-carbonyldiimidazole (CDI) to form an activated amide intermediate 5-[2-(1H-imidazol-1-yl)-2-oxoethyl] benzo[b]acridin-12(5H)-one(IEBA), which was a novel fluorescence probe.
