Photolithographic Olefin Metathesis Polymerization [PDF]
Journal of the American Chemical Society, 2013 Patterning functional materials is a central challenge across many fields of science. The ability to lithographically fabricate micro- and nanostructures has been one of the most impactful technological breakthroughs of the last century. In part due to the complexity of the chemical processes in photoresists, there is a limited variety of materials ...

A Review on Olefin Metathesis Reactions as a Green Method for the Synthesis of Organic Compounds
Journal of Chemistry, 2021 Olefin metathesis is a metal-mediated C-C bond exchange by which the two fragments within the olefin precursor are redistributed as a result of breaking the double bond to obtain a new product. Currently, most of the synthetic organic compounds, polymers,
