碩士 === 國立中央大學 === 化學研究所 === 99 === In order to study and discuss a single, double and triple bond in a variety of heterocyclic impact. Therefore, in this project which we designed and synthesized several new models of two-photon compounds. Then we measured the linear and nonlinear optical properties. And then by analyzing the model compounds with the observed optical properties, finally obtained useful information of molecular design. Include the use of double bonds to extend the conjugated structure can enhance the absorption of linear or nonlinear、quinoxaline-centered structure has absorbed over a wide range, and the pyrazine-centered structure has better absorption coefficient、Extended π-delocalization domain for linear and nonlinear optical properties have a good impact, and increased the number of branches in the external structure to 1,3,5-triazine centered structure of the molecule which has increased for the linear optical absorption wavelength range role.
