| 摘要 |
The invention relates to a chemiluminescent composition, i.e. one which emits light when its various constituent components are mixed together. The composition consists of at least two separate solutions of at least one oxalate, at least one fluorescent substance, hydrogen peroxide and at least one catalyst, in which those components which react together are kept separated. The characteristic of the 9,10-bis(phenylethynyl)anthracene is that the oxalate is a bis(dihalo-acylphenyl)oxalate. This compound is easily and economically produced and is easily soluble in the solvents used, to provide high-intensity light emission for long time periods. The 2,4- or 2,6-acyl substituted phenyloxalate also forms a subject matter of the invention.
