a CD spectra of sym-BCE[5] with increasing concentrations of LG and DG (0 to 1.1 equiv). b CPL spectra of sym-BCE[5]⊃LG (1:1) and LG (blue and black lines, λex. = 350 nm), sym-BCE[5]⊃DG (1:1) and DG (green and red lines, λex = 350 nm). c SEM images of sym-BCE[5]⊃DG (up) and sym-BCE[5]⊃LG (bottom). d CD spectra of LG, DG, sym-BCE[5]⊃LG (1:1), sym-BCE[5]⊃DG (1:1), sym-BCE[5]⊃LG + Na+ (1:1:1) and sym-BCE[5]⊃DG + Na+ (1:1:1).
