a Normalized FDCD spectra of BTA/R- or S-Ag6 (molar ratio 100:20). b Normalized FDCD spectra of BTA/R- or S-phol (100:7). c Normalized FDCD spectra of BTA/R-phol/R-Ag6 and BTA/S-phol/S-Ag6 (100:7:20). d PXRD patterns of BTA, BTA/S-phol (100:7), BTA/S-phol/S-Ag6 (100:7:0.5), BTA/S-Ag6 (100:0.5), and S-Ag6, d-spacing (unit: nm) corresponding to diffraction peaks. e GIWAXS pattern of BTA self-assemblies. f GISAXS pattern of BTA self-assemblies. g Illustration of the self-assembly process of achiral BTA molecule into homochiral helix mediated by chiral seed of R-Ag6 via chirality transfer, with amplified CPL through the synergistic chirality of R-phol. Note: The blue shadings in (a–c) indicate the signal region for BTA, and the orange shadings indicate the signal region for R/S-Ag6.
