Figure 4

Schematic representation of pH-chemical and pH-photochemical responsive release of cargo from the hydrophobic inner phase of MOP3 and MOP4, respectively. Please note the MOP3 and MOP4 differ from MOP2 in that octadecyl butanediammonium 5 is used to create MOP3 and octadecyl pentanediammonium ion 4 is used to create MOP4. The different affinities of 3 – 5 toward CB[7] provide the appropriate thermodynamics to create the pH-chemical and pH-photochemical responsive release.
