摘要：
Interaction of Coumarin 1, its 3-aldehyde derivative, and biscoumarin with solvents of varying acidity (water and ethanol with an alkali or acid admixture) was studied by following changes in their absorption and luminescence properties. The reasons for weak emission ability of neutral ethanolic solutions of 3-substituted derivatives of Coumarin 1 were revealed.
