fabrication (Rao et al. 2013). Considering the environmentally benign construction of desired systems, the use of eco-friendly solvents such as water has been
desirable. Würthner et al. prepared water-soluble and self-assembled nanocapsules
composed of perylene bisimide vesicles (Zhang et al. 2009). For this approach,
a small amount of THF solution of amphiphilic PBI1 and PBI2 (Fig. 12.14a)
was added slowly to an aqueous solution of guest bispyrene. Subsequently, these
loaded vesicles were stabilized by in situ photopolymerization using 2,2-dimethoxy2-pneylacetophenone under 350 nm ultraviolet irradiation. The characterization was
