Abstract : A great attention has been paid to organic non linear optical materials (NLO) due to theirpotential use in high speed electroptics (EO) coefficient, lower dielectric constants and easy preparation compared with in organic crystals (NLO) such as LiNbO3. In this project a non-isothermal decomposition studies are going to be conducted on tetracyanoquinodimethan with some organic compound and also with Rhodium acetate will be prepared in our laboratory. Characterization will be done by higher spectroscopic techniques. A thermogravimetery (TGA), Differential thermal analysis (DTA), X-Ray analysis (XRD) and differential scanning calorimetry (DSC) techniques will be employed. Variation of rate of heating are going to be used to calculate the activation energy (Ea) the frequency factor (Ln A), enthalpy (ΔH), heat capacity (Cp) and the entropy (ΔS) change. Furthermore the important optical properties will be measured and analyzed and compared with the obtained results.
