The article contains the following contents:
Spontaneous deracemization has been used to sep. homochiral domains from the racemic system. However, homochirality can only be referred to when the scales of these domains and systems are specified. To clarify this, we report self-assembly of racemates of dissym. cages DC-1 (I) with a cone-shape propeller geometry, forming a centrosym. columnar crystalline phase (racemic at crystallog. level). Owing to their anisotropic geometry, the two enantiomers are packed in a frustrated fashion in this crystalline phase; single-handed double helixes are observed (single-handedness at supramol. level). The frustrated packing (layer continuity break-up) in turn facilitates screw dislocation during the crystal growth, forming left- or right-handed spiral platelets (symmetry-breaking at morphol. level), although each platelet is composed of DC-1 racemates. The symmetry correlation between DC-1 mols., the crystalline phase and spiral platelets, all exhibit C3 symmetry. In addition to this study using 1-Bromo-3-iodobenzene, there are many other studies that have used 1-Bromo-3-iodobenzene(cas: 591-18-4Application of 591-18-4) was used in this study.
1-Bromo-3-iodobenzene(cas: 591-18-4) has been used in the preparation of 1-(3′-bromophenyl)-3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodec-1-ene and 1-(3′-bromophenyl)-3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooct-1-ene.Application of 591-18-4
