Trisubstituted alkenes featuring aryl groups: stereoselective synthetic strategies and applications

In recent years, the synthesis and application of alkenes have attracted increased attention. Triphenylethenes (TriPEs) have lower molecular torsion than tetraphenylethenes (TPEs), which helps to balance the degree of conjugation and the aggregation-induced emission (AIE) effect. The geometry of dou...

Description
Summary:In recent years, the synthesis and application of alkenes have attracted increased attention. Triphenylethenes (TriPEs) have lower molecular torsion than tetraphenylethenes (TPEs), which helps to balance the degree of conjugation and the aggregation-induced emission (AIE) effect. The geometry of double bonds has a significant impact on luminescence. Therefore, it is essential to provide a comprehensive summary of the stereoselective synthetic strategies for trisubstituted alkenes. In this review, common strategies for the stereoselective synthesis of alkenes are described, with an emphasis on the origin of stereoselectivity and the types of substrates. In addition, the AIE properties of TriPE and its applications in optoelectronic devices, stimuli-responsive materials, sensors, and therapies were discussed.
