Processes in which the self-assembling/disassembling of transition metal containing supramolecular structures can be controlled are reviewed. A distinction is made on the basis of the property which switches on/off the self-assembling or disassembling event: both pH-driven and electrochemically-driven processes are presented, with particular attention to metal helicates. In the case of the electrochemically driven disassembling/self-assembling of copper helicates, the possibility of tuning the potential at which the processes take place is presented, together with the hysteresis-like behaviour of some systems, which discloses their possible use as molecular memories.

Abstract
Processes in which the self-assembling/disassembling of transition metal containing supramolecular structures can be controlled are reviewed. A distinction is made on the basis of the property which switches on/off the self-assembling or disassembling event: both pH-driven and electrochemically-driven processes are presented, with particular attention to metal helicates. In the case of the electrochemically driven disassembling/self-assembling of copper helicates, the possibility of tuning the potential at which the processes take place is presented, together with the hysteresis-like behaviour of some systems, which discloses their possible use as molecular memories.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
