| Research Abstract |
We have developed the design of redox-active liquid crystals which allow us to switch molecular and assembled states simultaneously by means of electrochemical redox processes. We experimentally demonstrate that [M(L)(C10,8bpy)]n (L = redox-active ligand, n = 0 or +) shows versatility not only for mesogen for LC but also for thermochromism, emission, Lewis-acid binding, and redox-activity at LC phase. These physicochemical functions of the skeleton, in particular, appear at columnar LC phase, where the functional moieties play an essential role for constructing their physical structures. Therefore, the results could be foundational for developing chemical devices with the aid of the Coordination programming. In addition to the above results, we uncover novel features of coordination complexes with redox-active ligand, for example, redox-active metalloligand, photocatalytic hydrogen production, valence tautomerism coupled with macroscopic phase, and multiresponsive chromism.
