Chemists have succeeded in specifically controlling the setup of precision polymers by light-induced chemical reactions. The new method allows for the precise, planned arrangement of the chain links, ...

Polymers are also called macromolecules, being very large organic molecules composed of an extremely high number of repeating smaller units called monomers. Their applications are widespread, and ...

Mastering how to completely control the exact monomer sequence of synthetic polymers is the ultimate key for establishing true biomimetic macromolecular chemistry. A versatile one-pot approach for the ...

A new method allows chemists to precisely place single monomers at any position within a polymer chain made of other types of monomers. With this single monomer, chemists can add various types of ...

Yttrium-based catalysts can be used to stitch together two different lactone monomers in an alternating fashion to produce polyesters with well-defined primary structures. The ability to control the ...

This illustration shows the C1 polymer formation, where the Pd-catalyst (red spere) is linearly combining a number of diazoacetate monomers (transparent sphere) to form the polymer main chain. For ...

Smashing compounds together to get them to polymerize sounds more like desperation than effective organic chemistry. But chemists Timothy M. Swager of Massachusetts Institute of Technology and Jens B.

The synthesis and self-organization of biological macromolecules is essential for life on earth. Chemists now report the spontaneous emergence of complex ring-shaped macromolecules with low degrees of ...

This ultimate goal of this project is to develop advanced drug delivery systems, which combat diseases by effectively sending "targeted bombs" to disease sites. Project is Not Currently Available This ...
