The construction of externally switched solid-state devices awaits development of molecular junctions sandwiched between two electrodes [89]. They may, for example, consist of CyD-based meccano molecules such as rotaxanes (discussed in Chapter 12) for which switching in the solution phase or in monolayers has been demonstrated [21].
