Abstract:

Described in the synthesis of two spiro core segments of orthogonally arranged conducting systems. The final systems are to have a potentially conducting chain fused perpendicularly to a second potentially conducting chain via a sigma bonded network. These systems may be suitable for incorporation into future molecular electronic devices. One of the core segments synthesized is based on a thiophene conducting group and it is formed by a zirconium-promoted bisbicyclization of bisdiene systems. The second is a phenylene-based system which is derived from fluorene. Terminal bromide groups provide the linkage points for further extensions of the chains via palladium-catalyzed cross coupling methods.
