Chromogenic/Fluorogenic Ensemble Chemosensing Systems

Researchers discuss chromogenic/fluorogenic ensemble chemosensing systems. An ensemble chemosensing system can be broadly defined as the formation by two or more precursor molecules of a supramolecular ensemble by means of noncovalent interactions, which interacts with foreign species, causing significant changes in optical signals, depending on whether or not the indicator is released from the ensemble. The researchers begin their discussion by describing the design principles and a systematic classification of supramolecular ensembles. They also state that chemical sensing is one of the main achievements in advances in supramolecular ensembles.
