type of ancillary ligand, solvent, and outer-sphere counteranions. In dichloromethane, reversible chelation and partial displacement of the P,N coordinating moieties allow for toggling between aminoazobenzene- or pseudostilbene- and azobenzene-type derivatives. The reversibleswitching between electronicstates of azobenzene can be controlled through either addition or extraction of chloride counterions
deals with azodyes naturalisedthroughglycoconjugation with a very common saccharide – lactose – and with its galactose and glucose components. The conjugation takes place through a bifunctional linker, here a terminal dibromoalkane, so the final products are very stable diether derivatives of the starting dyes. These transformations produce naturaliseddyes – indeed, water-soluble and multipurpose
