Visual detection of nitro-explosives by using 10-(4,5-di-p-tolyl-1H-1,2,3-triazol-1-yl)-2,3-dimethoxypyrido[1,2-a]indole

10-(4,5-di-p-Tolyl-1H-1,2,3-triazol-1-yl)-2,3-dimethoxypyrido[1,2-a]indole 2 was obtained by interaction of 5,6-di-p-tolyl-3-(2-pyridyl)-1,2,4-triazine 1 with 4,5-dimethoxydehydrobenzene. The fluorescence properties of the compound 2 in the presence of nitroaromatic compounds were studied.
