Antiviral activity of singlet oxygen-photogenerating perylene compounds against SARS-CoV-2: Interaction with the viral envelope and photodynamic virion inactivation

Virus Research, 2023
The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has prompted great interest in novel broad-spectrum antivirals, including perylene-related compounds.

Molecular Doping of CVD-Graphene Surfaces by Perfluoroalkyl-Substituted Perylene Diimides Derivatives

Nanomaterials, 2022
Non-covalent π-π and dipolar interactions with small aromatic molecules have been widely demonstrated to be a valid option to tune graphene work functions without adding extrinsic scattering centers for charge carriers.

Light-Harvesting Metal-Organic Frameworks (MOFs) La-PTC for Photocatalytic Dyes Degradation

Bulletin of Chemical Reaction Engineering & Catalysis, 2021
A novel porous metal organic framework, La-PTC was synthesized by solvothermal method using a perylene-3,4,9,10-tetracarboxylate ligand and lanthanum metal ion. The FTIR analysis showed that La-PTC has a different structure with PTCDA and Na4PTC.

Dyes with high dielectric constants [PDF]

, 1988
The dielectric constants of perylene dyes, perylene-3,4: 9,10-tetracarboxylic bisimides, are reported. With aromatic substituents, dielectric constants up to 110 are obtained. With polymeric dyes, the dielectric constants rise to 260.

Leichtlösliche, lichtechte Perylen‐Fluoreszenzfarbstoffe [PDF]

Chemische Berichte, 1988
AbstractDie Synthese von Perylenfarbstoffen 2 mit terminalen Alkylgruppen wird beschrieben. Langkettige n‐Alkylgruppen führen nicht zu einer Erhöhung der Löslichkeit, sondern zu einer Erniedrigung. Cycloalkyl‐Reste bewirken ein Minimum an Löslichkeit im Bereich der mittleren Ringe und ein Maximum beim Cyclotetradecyl‐Rest (2p).
