Influence of side chain characteristics on the aggregation-induced emission (AIE) properties of tetrasubstituted tetraphenylethylene (TPE)

Abstract

[EN] Five new tetraphenylethylene (TPE) derivatives were synthesised and their aggregation-induced emission (AIE) was evaluated in mixtures of THF/water and MeOH/water. The influence of regiochemistry and length of the chains in the substituents on emissive properties was studied. ; We thank the Spanish Government, FEDER funds (MAT2015-64139- C4-1-R and MAT2015-64139-C4-4-R) and the Generalitat Valenciana (PROMETEOII/2014/047) for support. ; Ceballos-Fernández, SA.; Gil Grau, S.; Costero, AM.
