Abstract
A two-stage method of converting aromatic nitro compounds into luminophors is proposed. It includes catalytic reduction of the nitro aromatic compound by molecular hydrogen followed by the interaction of the formed aromatic amine with a fluorogenic reagent (fluorescamine, ortho-phthalaldehyde). Efficient reduction is provided by using palladium catalysts on supports with developed surface, such as barium sulphate, C60 fullerene, and microcapillary glass plates. Luminescence of the final products is observed in the regions l = 490
