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. WebJun 21, 2024 · Typical AIEgens, such as hexaphenylsilole (HPS) and tetraphenylethene (TPE), have been well studied (Fig. 1) 18, 19, 20. In solution, the dynamic rotations of the phenyl rings in TPE as a...

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. WebA couple of water-soluble chiral 2,6-helic[6]arene derivatives P-H1 and M-H1 were synthesized, and they could form 1:1 stable complexes with 4-[(4′-N, N-diphenylamino)-styryl]-N-methylpyridinium iodide (G) in water. Compared with G, the host-guest complexes exhibited enhanced fluorescence, which might be attributed to the spatial confinement of … ips click

Herein, we present a strategy to construct chiral organic cages by restricting the Por Mrotational configuration of tetraphenylethylene (TPE) faces through dynamic covalent chemistry. WebAug 1, 2024 · Most of AIEgens are symmetrical and achiral. For studying the chiral recognition and chiroptical properties, a wide variety of chiral AIEgens and chiral AIE systems have been developed. The simple and direct method is to introduce optically pure groups into AIE molecules or AIE polymers. orca baker \u0026 butcher lasalle\u0027s avenue
