A hydroxyl group is situated ortho to a carboxyl group which as a bidentate ligand is terminally metallized on the fiber when aftertreated with dichromate. An example is Alizarine Yellow GG [584-42-9] (50) (Cl Mordant Yellow 1 Cl 14025). Cr(III) has a coordination number of six, and therefore normally two dye molecules of the sahcyhc type are chelated to the metal ion.

The applicability of the supramolecular approach for SRG recording has been demonstrated by combination of different charged azobenzene derivatives with different polyelectrolytes. Such azobenzene derivatives as Brilliant Yellow, Alizarin Yellow GG, and Methyl Red, all commercially available, have been used as active components. The chemical structures of the compounds are shown in Fig. 2.7. Note that the absorption may be tuned by a proper selection of the dye component that can match specific applications where given laser wavelengths must be used.
