a Self-assembly of BTA molecules into racemic nanoribbons. b Introduction of small doses of R/S-Ag6 clusters triggers the formation of helical nanoribbons through chirality transfer. c The helical nanoribbons serve as chiral/energy donors and assembly templates, co-assembling with R/S-Ag6 clusters (first acceptor) and R/S-Cu6 clusters (second acceptor), with a synergistic effect of R/S-phol to construct chirality-controlled LHSs exhibiting high glum and broad CPL spectral range.
