Extended Orthogonally Fused Conducting Oligomers for Molecular Electronic Devices
Abstract
Described is an approach to orthogonally fused conjugated organic compounds that may act as molecular switching devices. Four thiophene trimers are added in a single operation to spiro-fused cores to afford the target molecules. A spiro-fused thiophene-based monomer system is converted to a spiro- fused heptamer that is 25 A long. The synthesis of a mixed phenylene-thiophene system is described that provides a spiro-fused octamer that is 30 long. In each case, alkyl substituents on the thiophenes afford soluble materials. Trimethylsilyl end groups flank each orthogonally fused system. Organophalladium- and organonickel-catalyzed procedures are used extensively for the synthesis of the orthogonally fused compounds.
