Supramolecular aggregation and disaggregation induced by external stimuli can impact the optical or electrical signals of the aggregates/constituting units (receptors). Therefore, manipulating supramolecular aggregation/disaggregation has recently been employed to construct novel and promising photoluminescence (PL)‐based sensing and recognition systems. The sensing systems were capable of substantially enhancing the sensitivity, relying on cooperative interactions occurring in the assembly/disassembly processes (mostly operating in emission turned‐on or emission‐enhanced mode). This review focuses mainly on recent advances in the new emerging PL‐based sensing platforms, based on manipulating the behaviours of supramolecular aggregation/disaggregation, including aggregation‐induced emission (AIE), metallophilic interactions‐related sensing (metallophilic interactions‐induced aggregation/disaggregation), metal coordination polymers‐related sensing, and other sensing systems involving supramolecular aggregation/disaggregation. In particular, those sensing systems developed by scientists in China are summarized and highlighted. Copyright © 2011 John Wiley & Sons, Ltd.
