Chirality
Two main strategies are usually used to achieve optical resolution of Ru(II) complexes :
A new method has also been recently developped by von Zelewsky et al. which is based on a new class of ligands called CHIRAl GENerators ligands or CHIRAGEN [5]. These CHIRAGEN ligands are able to transfer their chirality to metal centers and, in this way, a predetermination of the absolute configuration L and D at the metal center can be reached.
