主 题：Aggregation-induced emission Chirality Macrocycles Circularly polarized luminescence Luminescence
摘 要：Herein,a pair of chiral macrocyclic luminogens derived from chiral 1,1-bi(2-naphthol)(BINOL)and tetraphenylethenes(TPEs)have been prepared with high yield via intramolecular McMurry coupling,in which the preferential helicity of propeller-shaped TPE units can be tuned via choosing proper chiral BINOL tethers.The preferential chiral geometry of the macrocyclic luminogen was unambiguously confirmed by X-ray crystal crystallography and theoretical calculation,whereas the variable-temperature NMR spectra and chiral HPLC analysis further verified the intramolecular motions.These two chiral macrocyclic luminogens both exhibit obvious aggregation-induced emission behavior and mechanochromic luminescence properties.Furthermore,aggregation attenuated CD signals and circularly polarized luminescence were observed for these two chiral macrocylic luminogens in THF-water mixture and PMMA matrix.These results had paved a new approach toward constructing chiral aggregation-induced emission luminogens(AIEgens)and their structural engineering.
