실험 절차

First, 2.16 g of phenylglyoxal and 3.36 g of 9,10-diaminophenanthrene were dissolved in a solvent of 100 mL of dehydrated ethanol under a nitrogen atmosphere. The solution was refluxed for 7 hours to be reacted. The white power precipitated through the reaction was filtered. The residue was washed with ethanol and then ether to give a dibenzo[f,h]quinoxaline derivative, Hdbq-P, which was the target substance (yield: 92%). Synthesis scheme of Step 1 is shown in (a-1) below.
