a Schemes for the preparation of complex 2D BCMs by sequential addition of two unimers (P210 and P215). By changing the order of the unimer addition, two types of symmetric penta-BCMs were obtained. The 2D nanosheets of longer P215 unimers are shown in dark pink, and those of P210 unimers are shown in light pink. b TEM images, c electron density profiles, and d 2D, and 3D height AFM images of the penta-BCMs showing clear distinctions of the two types of penta-BCMs prepared by the sequential addition. e Scheme for the preparation of one 2D BCM by one-shot addition of two unimers. f TEM image and electron density profile of the penta-BCM obtained by one-shot living CDSA. Numbers in the images indicate the average length (Ln) and dispersity (ĐL).
