ABSTRACTA series of substituted phenylene ethynylene diazonium salts were prepared from the corresponding anilines by the action of nitrosonium tetrafluoroborate in sulfolane-acetonitrile solvent. Formation of self-assembled layers of the diazonium salts in acetonitrile solution was demonstrated on Au, Cu and Pt surfaces. The self-assembly rate of the diazonium salts was found to be markedly dependent on the electron withdrawing character of the substituents attached to the aromatic rings.

Chiral oligo(methylene-p-phenyleneethynylene)s can form vesicular assemblies no matter whether side chains and solvents are hydrophilic or hydrophobic. The self-assembly processes are highly independent of molecular design and chemical environments.

Image Processors

Recent advances in chemical self-assembly will soon make it possible to synthesize extremely powerful computing machinery from metallic clusters and organic molecules. These self-organized networks can function as Boolean logic circuits, associative memory, image processors, and combinatorial optimizers. Computational or signal processing activity is elicited from simple charge interactions between clusters which are resistively/capacitively linked by conjugated molecular wires or ribbons. The resulting circuits are massively parallel, fault-tolerant, ultrafast, ultradense and dissipate very little power.
