New Chemo-/Biosensors with Silole and Tetraphenylethene Molecules Based on the Aggregation and Deaggregation Mechanism

Recent advances in the design and development of fluorescent chemo/biosensors by making use of aggregation-induced emission (AIE) of silole and tetraphenylethylene are summarized. The AIE sensing is mostly achieved by manipulating the aggregation or deaggregation of AIE luminogens. In addition, the perspectives of chemo/biosensing and imaging with AIE molecules are discussed.
