- 摘要：Biomaterials in nature often exhibit hierarchical
chiral structures with an intriguing mechanism involving
hierarchical chirality transfer from molecular to supramolecular
and the nano- or microscale level. To mimic the cross-level
chirality transfer, we present here one kind of host−guest complex
system built of β-cyclodextrin (β-CD), sodium dodecyl sulfate
(SDS), and fluorescent dyes, which show multilevel chirality,
including molecular chirality of β-CD, induced supramolecular
chirality of β-CD/SDS host−guest complexes, a chiral lattice selfassembled nanosheet, mesoscopic chirality of an assembled helical
tube, induced chirality of a dye-doped chiral tube. The hierarchical
chirality involved a chiral lattice self-assembly process, which can
be identified by small-angle X-ray scattering, optical studies, circular dichroism, and circularly polarized luminescence spectral
measurements. Benefiting from the chiral lattice self-assembly, intense circularly polarized luminescence was observed from
the achiral dye-doped complexes with a large dissymmetry factor up to +0.1. This work thus provides a feasible insight for
developing hierarchical chiroptical materials based on the lattice self-assembly
