Triggering assembly associated with supramolecular isomers have different structures but an identical chemical composition have received increasing attention in the area of coordination chemistry and crystal engineering using metal ions.
A range of examples of triggering assembly in supramolecular coordination compound systems have been investigated and several factors such as temperature, pressure, light, solvent, template, guest, pH, catenation, molar ratio and concentration have been found. The influence of controlling factors on the formation of supramolecular coordination compounds has been studied extensively by many research groups.
Supramolecular coordination polymer materials with multi-stable systems between multi states, usually triggered by external stimuli, such as temperature, light, pressure and guest inclusion, are a family of potential candidates for smart materials because the changes of chemical and physical properties are very large. Various supramolecular coordination compounds, especially those with polymeric 1D, 2D and 3D frameworks, have been intensively investigated since their polynuclear geometries linked framework structures enhance cooperative effects which link to their potential technological applications as components of memory devices, displays and sensors so on. Now various sophisticated and expensive technique can be used for triggering assembly of supramolecular coordination compounds.
In this section, we would like to discuss several aspects of “triggering assembly of supramolecular coordination compounds” with various researchers who have been developing this field deeply and extensively.
