In this report the effects of 3CN substitutions on the spectral luminescence and lasing properties of oxy- and diethylaminocoumarins are studied. In both classes of coumarins the CN group decreases the tuning region of hte maximum lasing wavelengths: in aminocoumarine as a result of decreased intermolecular interaction with the solvents, and in the oxy- as a result of a shift in the equilibrium of protolytic reactions towards anion forms. As a result, the lasing efficiency of anion forms of 3CN oxycoumarins increases. The lasing properties of aminocoumarins decrease with the given substitutions, while the probability increases for the formation of nonplanar molecular conformations.
