Figure 3. Controlled coordination-driven hierarchical self-assembly.

Figure 3

(a) Dependence of the percentage of micelles that aggregate into linear fibres on initial micelle concentration, 24 h after addition of Pd2(dba)3 (0.4 equiv. Pd(0)). Labelled points (b,e) correspond to TEM images (b,e), respectively. (b) TEM image of M545 (0.05 mg ml−1) 24 h after addition of Pd2(dba)3. (c) Schematic depiction of the intermicelle crosslinking between the coronas of two adjacent but offset micelles. (d) Mean fibre length (Ln) as a function of normalized Pd(0) concentration for the coordination-driven hierarchical self-assembly of cylindrical BCPP micelle subunits M545 (Ln=545 nm, Lw/Ln=1.05; red data points) and M970 (Ln=970 nm, Lw/Ln=1.04; blue data points) at 0.5 mg ml−1 in EtOAc (see Supplementary Fig. 21 for an enlarged graph). Labelled points (e,f) correspond to TEM images (e,f), respectively. (e) TEM images of M545 (0.5 mg ml−1) 24 h after addition of Pd2(dba)3 (0.4 equiv. Pd(0)). (f) TEM images of M970 (0.5 mg ml−1) 24 h after addition of Pd2(dba)3 (0.4 equiv. Pd(0)). Scale bars correspond to 5,000 nm in main images and 1,000 nm in insets.
