X-ray diffraction analysis is made by Leka and friends and theoretical results are calculated by density funct,onal theory, B3LYP model and 6-311G(d,p) bases set. The geometric parameters obtained as a result of the optimization of the structure were successfully represented by X-ray diffraction method and all theoretical calculations are used by the the same method of DFT/B3LYP/6-311G(d,p). Chemical activity parameters of the optimized structure, molecular electrostatic potential map, Fukui functions and net charge analysis were used to obtain electrophilic and nucleophilic nature of the structure as well as hardness and softness information. Nonlinear optical properties were examined and the tendency of the structure to be an optical material was discussed. In addition, the interactions of DNA bases adenine, guanine, cytosine and thymine with the studied molecule were determined by electrophilic charge transfer (ECT) method.4-Etoksi-3-Metoksibenzaldehit molekülü biyolojikaktivitelerinin yani sira hetero halkali bilesiklerin sentezlenmesinde oldukçabüyük bir öneme sahiptir.
