Synthesis of a Benzolactone Collection using Click Chemistry.
Estrogenic Analogues Synthesized by Click Chemistry.
When it comes to understanding the physical structure, chemical properties and composition of materials, no scientific services company offers the breadth of experience, diversity of analytical techniques of technical ingenuity of EAG. From polymers to composites, thin films to superalloys—we know how to leverage materials sciences to gain a competitive edge. At EAG, we don’t just perform testing, we drive commercial success—through thoughtfully designed investigations, technically superior analyses and expert interpretation of data.
Modular Synthesis of ABC Type Block Copolymers by "Click" Chemistry.
Quenching of Kumada–Tamao catalyst-transfer polymerization with ethynylmagnesium chloride gives poly(3-hexylthiophene) (P3HT) having mono- and di-capped ethynyl end groups; consequently, diblock copolymer synthesized by click reaction with another azide-ended polymer is contaminated with tri-block polymer. Post end-modification of P3HT having H/Br end groups by Sonogashira coupling and deprotection exclusively gives P3HT ethynyl-functionalized at one end, enabling synthesis of uncontaminated diblock copolymer.

Scientists at Lawrence Berkeley National Laboratory's (Berkeley Lab) Molecular Foundry, a facility that specializes in nanoscale science, worked with a team led by Sharpless and Peng Wu, professors at the Scripps Research Institute (TSRI). The team created long chains of linked sulfur-containing molecules, termed polysulfates and polysulfonates, using a SuFEx click reaction.
Polymeric materials via click chemistry.
"Click chemistry is a powerful tool for materials discovery, but synthetic chemists are often not well-equipped to characterize the polymers they create," said Yi Liu, director of the Organic Synthesis facility at the Molecular Foundry. "We can provide a broad spectrum of expertise and instrumentation that can expand the scope and impact of their research."
