Automated Flow Technique Makes Length- And Sequence-Specific Polymers

Traditional synthetic polymers contain a distribution of chain lengths and monomer sequences. For applications such as molecular electronics, however, scientists want to create polymers of a specific sequence and length—a difficult task. Frank A. Leibfarth, Jeremiah Johnson, and Timothy Jamison at MIT have now developed Flow-IEG (flow synthesis and iterative exponential growth), a semi-automated coupling… Read more »
