Abstract: The design of molecules with delocalized π-electronic structures which are useful as organic conductor and light-emitting diodes(LEDs) has attracted much attention.^[1-2] We have synthesized some conjugated Schiff base macrocycles containing 1,3,4-oxadiazole(such as compound 1) and after being doped with I₂,they showed electrical conductivity in the region of semiconductor.^[3] To continue this work and understand the relationship between molecular structure and solid state properties, we designed other conjugated schiff base macrocycle containing 1,3,4-oxadiazole.
