Interative Divergent/Convergent Doubling Approach to Linear Conjugated Oligomers.A Rapid Route to a 128 A Long Potential Molecular Wire and Molecular Alligator Clips

摘要

The ultimate computational system would consist of logic devices that are ultradense, ultra fast, and molecular-sized. Even though state-of-the-art nanopatterning techniques allow lithographic probe assemblies to be engineered down to the 100 A gap regime, the issue of electronic conduction based upon single or small packets of molecules has not been addressed and the feasibility of molecular electronics remains theoretically controversial. In an attempt to assess the possibility of molecular wire conduction by spanning the 100 A probe gaps with small packets of molecules, we describe here the synthesis of phenylene-alkynylene oligomers that remain in a near-linear conformation due to 1,4-
