Abstract:

Discotic liquid crystals (DLCs) are of great interest because of both their unique self-assembled structures and their potential applications in organic devices such as field-effect transistors and photovoltaic solar cells, due to the high chargecarrier mobility along their one-dimensional (1D) aromatic _-_ stacking. Derivatives of 1,2,4- oxadiazoles have potential for application in advanced materials, as they present large dipole moments, charge-transport abilities besides blue fluorescence. However, such compounds have not been studied extensively in terms of their material properties. In this work, the synthesis of some halfdisc shaped molecules containing 1,2,4-oxadiazole and the study regarding the relationship between chemical structure and mesomorphic behavior, thermal and optical properties is reported.
