Efficient Fenton Degradation of Perylene Diimide Dye Promoted by a Catalytic Amount of Cucurbit[8]uril

“…The Fenton reaction is considered as a promising technology for dye degradation. The Fenton reaction refers to the complete oxidation of aromatic compounds by a combination of hydrogen peroxide (H 2 O 2 ) and ferric salts, which is widely applied in the degradation of polycyclic aromatic dyes in water. − However, for some polycyclic aromatic dyes with extended π-conjugates, such as perylene diimide dyes, − , the efficiency of the Fenton reaction is severely reduced because of the severe self-aggregation in aqueous solutions. Therefore, it is desirable to develop new methods to promote the Fenton degradation of perylene diimide dyes.…”

Concepts and principles of self-n-doping in perylene diimide chromophores for applications in biochemistry, energy harvesting, energy storage, and catalysis

“…It has been shown that N-PDIs are capable of chiral self-assembly to form various structures such as supramolecular helices and can further be used as biologically-based chiral sensors. [148][149][150][151][152][153] For example, N-PDI's photoluminescence and electroluminescence properties can be tuned in both turn-on and turn-off sensing of various analytes such as nucleic acids, tumor markers, proteins, and drugs. [154][155][156][157][158][159][160] The relationship between N-PDIs and DNA has been the subject of the most widespread investigation due to its role in disease and the emerging interest in using DNA as a molecular wire, data storage, and other electronics applications.…”

Chirality of Perylene Diimides: Design Strategies and Applications

“…The Zheng group proposed that different configurations of π‐π stacking between the phenyl groups of the amino acids leads to chiral inversion. Wang and co‐workers reported a PDI functionalized with boronic acid that forms dynamic covalent bonds with the cis ‐diol unit of the chiral anticancer drug 5′‐deoxy‐5‐fluorouridine [53] . A highly ordered right‐handed helical assembly was formed, and the pH‐responsive dynamic covalent bonds were stable upon heating.…”
