The new bis-hydrazone based ligands A and B form ionisable [2 × 2] grid-type transition metal complexes whose properties may be modulated by multiple protonation/deprotonation as shown by the reversible change in optical properties of the [CoII4L4]8+ complexes depending on their protonation state.

金属络合物,其性质可通过多次质子化/去质子化进行调节,正如[CoII4L4]8+络合物光学性质的可逆变化所显示的那样,这取决于其质子化状态。
