Phenanthroline and its derivatives supramolecular compounds are an important part of a 1,10 - phenanthroline ligand complex to have good optical properties, can be used as a catalyst for light meter and light. 1,10 - phenanthroline -5,6 - dione as a thick heterocyclic ligand conjugate, both characteristics of a good coordination is also important intermediates in organic synthesis reaction, the derivatives of the compounds with the metal ion complexes formed can be used for anti-cancer drugs, DNA probes, non-linear optical materials, supramolecular assembly of the molecular skeleton, Spin Crossover Complex and many other fields, which for its synthesis of research on the cause of the high degree of importance. In this paper, to 1,10 - phenanthroline used as starting material under the ice bath three neck flask by adding concentrated sulfuric acid, stirring, followed by adding potassium bromide and concentrated nitric acid at room temperature, stirring, heating to 130 ℃, reaction tem
