Interestingly, after supramolecular assembly with 4-sulfocalix [4]arene, the obtained complexes showed enhanced enantioselectivity for chiral acids.

Circularly Polarized Luminescence in Chiral π‐Conjugated Macrocycles

WebGenerally, the most effective strategy to design a chiral AIE luminogen (AIEgen) is to attach a chiral scaffold to an AIE-active fluorophore through covalent bonds. Moreover, some propeller-like or shell-like AIEgens without chiral units exhibit latent chirality upon mirror image symmetry breaking. Web2.1 Chiral AIEgens The modi cation of AIEgens with chiral groups is a widely adopted strategy to construct chiral AIEgens. In this section, we focused on the molecular structures of recently reported chiral AIEgens. Among them, 1-methyl-1,2,3,4,5-pentaphenyl-silole and TPE as two classical AIEgens have been popularly utilized. dallas mavericks tickets seating chart https://stormenforcement.com
