Since the aggregation-caused quenching of fluorescence (ACQ) is undesirable to practical applications, many research groups have made numerous efforts to solve this problematic issue. An unusual luminogen system in which aggregation enhanced fluorescence favorably instead of destructively, in the conventional systems was discovered in 2001 by Prof. Tang. As emission is triggered by aggregate formation, this phenomenon was termed as aggregation induced emission (AIE). AIE is a photo-physical effect about the light emission in the practically useful solid state, thus, the AIE studies may also lead to hitherto impossible technological innovations. A large number of AIE systems have been designed and developed, and their emission colors almost cover the entire visible regions with luminescence efficiency up to unity. The exploration of the AIE effect in the areas of optoelectronics and sensory systems has attracted increasing interest. As AIE luminogens are emissive in the aggregated state, they are very promising to be used as fluorescence sensors for cell imaging and explosive detection.
