The value of the second-order harmonic generation for the powder of 10-alkylacridones, synthesized by using acridone, was measured by using Nd: YAG as a laser source and the results show that these compounds have a good nonlinear optical property and the differences of the volume and electron property for the different substitutents on 10-position have a little effect on their values of second-order harmonic generation(SHG).
