Siloles are a group of silicon-containing five-membered cyclic dienes.Due to their unique electronic structures,they have been attracted much attention and potentially applied in many fields.In this review,we summarized recent progress in the synthesis of silole compounds and their applications as electroluminescent devices（EL）,chemsensors,biosensors etc.Opposite to common phenomenon of aggregation-caused quenching（ACQ） of light emission in many luminophoric molecules,silole compounds exhibit aggregation-induced emission（AIE）.Enlightened by this abnormal phenomenon,the applications of silole compounds are extremely extended,including traditional EL materials,chem-,bio-sensors and many fields in progress.At last,the future research of this research field is also prospected.
