WebJan 20, 2024 · Here, the authors report a strategy to achieve multicolor CPOA through chiral clusterization by inserting a chirality center into a non-conjugated organic cluster.
WebThe rule of thumb is: chiral carbon centers are carbon atoms that are attached to four different substituents, that are placed at the corners of a tetrahedron. Chiral carbon … 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 … WebDec 6, 2024 · The Cover Feature shows three representative chiral macrocycles and their mirror images reflected in a lake. Chiral macrocycles have an aesthetically pleasing stereogenic structure without a chiral carbon centre. These cyclic structures exhibit remarkable circularly polarized luminescence.
