The divalent organic cation, methyl green (MG), undergoes a slow transformation (6 h) to a monovalent cation, carbinol (MGOH + ) upon dilution of its solution (10 mM), or in a buffer at neutral pH. Adsorption isotherms of MG on montmorillonite were determined by two procedures, both of which yield a

In the title compound, C~9~H~7~NOΒ·C~4~H~6~N~2~, the imidazole ring is twisted away from the quinoline ring system with a dihedral angle of 60.8β (1)Β°. The crystal packing is stabilized by NβH...O, NβH...N, OβH...N hydrogen bonds and CβH...Ο interactions.
8-Hydroxy quinoline was coupled with half diazotized p-pheylene diamine. Complexes of Cu 2/ , Ni 2/ , Zn 2/ , and Co 2/ were prepared with the resulting dye-ligand. The complexes were then covalently bound into a crosslinked polymer matrix based on styrene-acrylamide copolymer through the ligand moi
