WebThe rule of thumb is: chiral carbon centers are carbon atoms that are attached to four different substituents, that are placed at the corners of a tetrahedron. Chiral carbon atoms are also referred to as ‘stereogenic carbons’ or ‘asymmetrical carbon atoms’. Compound 1 has a chiral carbon center, because it is attached to four different ... WebThe most obvious approach to obtaining chiral plasmonic nanostructures is to induce chirality at the level of the nanoparticle itself. 83–85 In most cases, a chiral molecule or biomolecule, such as an amino-acid, is used as a template to induce the chiral shape during nanoparticle synthesis. 86 For example, H. Lee et al. employed amino-acids ...
