Synthesis of Cucurbit[7]uril-linked Porphyrin-based complex. The free TPP porphyrin was first conjugated to hydrophilic polyethylene glycol after which the resulting conjugate was complexed with that of Cucurbit[7]uril. This reaction resulted in a self-assembling amphiphilic system. Adapted with permission from Özkan et al. (2019).
