Jean M.J. Fréchet (born August 1944) is a French-American chemist and professor emeritus at the University of California, Berkeley.
This widely used patented technology [8] which enables the extreme miniaturization of microelectronic devices is now ubiquitous for the fabrication of the very powerful computing and communication equipment in worldwide use.
In 1990 working with Craig Hawker at Cornell, he developed the convergent synthesis of dendrimers [10] as well as approaches to hyperbranched polymers.
[11] In 1992, working with F. Svec at Cornell, he reported the first preparation of macroporous polymer monoliths [12] that are now used in a variety of chemical separations.
Later work at Berkeley saw the development of polymers and dendrimers as carriers for targeted therapeutics [13] and successful approaches to new organic materials for transistors and solar cells.
