Abstract

The syntheses of soluble oligo (3-ethyl-2, 5-thiophene ethynylene) s via an iterative divergent/convergent approach starting from 3-ethyl-2-(trimethylsilylethynyl) thiophene are described. The monomer, dimer, tetramer, octamer, and 16-mer were synthesized. The 16- mer is 100 Å long in its minimized extended zigzag conformation. At each stage in the iteration, the length of the framework doubles. Only three sets of reaction conditions are ...
