Figure 6.

(a) A schematic illustration of the various responses of the multistimuli responsive system in Figure 5, demonstrating that the pathway of stimulus addition controls the morphology of the resulting composites. Conditions: (i) cool; (ii) heat; (iii) addition of Zn²⁺, heat; (iv) addition of Tpy, heat; (v) addition of Zn²⁺; (vi) addition of Tpy. (b) TEM images of the assembly induced by coordination interactions only (left) and hydrogen bonding interactions only (right). (c) SAXS traces for the HW-Tpy and CA-based multistimuli responsive NCT assemblies under different conditions, where the difference in interparticle spacings demonstrates the pathway-dependent nature of the assembly process.
