Abstract

The iterative divergenticonvergent approach to doubling the length of the molecule is shown in Scheme 1. Just three different reactions are needed at each stage to double the molecular length, rSc. d. 91 We initially conducted the synthesis starting from the monomer 1, assuming that ethyl groups would provide sufficient solubility to permit formation of a 16-mer long enough to bridge the lithographically derived probe gaps. Unfortunately, the octamer ...
