Membrane-Targeting Perylenylethynylphenols Inactivate Medically Important Coronaviruses via the Singlet Oxygen Photogeneration Mechanism

Molecules, 2023
Perylenylethynyl derivatives have been recognized as broad-spectrum antivirals that target the lipid envelope of enveloped viruses. In this study, we present novel perylenylethynylphenols that exhibit nanomolar or submicromolar antiviral activity against

Bending‐Induced Vibrational Landscape Reorganization Governs Energy Dissipation in Perylene Bisimides

Angewandte Chemie, EarlyView.
Gradually bent perylene bisimides (PBIs) isolate structural distortion as the sole variable and exhibit negligible intersystem crossing, uncovering rapid vibrational dephasing as the dominant driver of internal conversion through excited‐state vibrational landscape reorganization.

Iterative Synthesis of Pyrene–Coronene Molecular Graphene Nanoribbons

Angewandte Chemie, EarlyView.
An iterative approach delivers a new family of undoped, cove‐edged graphene nanoribbons with lengths up to 9.1 nm that exhibit both molar absorptivity and fluorescence brightness values on the order of 105 M−1 cm−1 and an intrinsic charge‐carrier mobility of 475 ± 32 cm2 V−1 s−1.

Photothermal Perylene Bisimide Hydrogels

Chemistry – A European Journal, 2023
AbstractGels formed using a perylene bisimide (PBI) as a low molecular weight gelator can show the photothermal effect. Formation of the PBI radical anion results in new absorption bands forming, meaning that subsequent irradiation with a wavelength of light overlapping with the new absorption band leads to heating of the gel. This approach can be used

Perylene-Based All-Organic Redox Battery with Excellent Cycling Stability

, 2016
Organic materials derived from biomass can constitute a viable option as replacements for inorganic materials in lithium-ion battery electrodes owing to their low production costs, recyclability, and structural diversity. Among them, conjugated carbonyls

Electrochemically Triggered Supramolecular Polymerization Under Kinetic Control

Angewandte Chemie, EarlyView.
Chemical and electrochemical stimuli enable controlled supramolecular polymerization of perylene diimide–histidine (PDI–His). Redox processes mediate the transformation of kinetically trapped aggregates into thermodynamically stable nanofibers, thereby supporting seeded growth. This approach provides a strategy for regulating self‐assembly pathways and

Perylene‐Mediated Electron Leakage in Respiratory Chain to Trigger Endogenous ROS Burst for Hypoxic Cancer Chemo‐Immunotherapy

Advanced Science, 2023
Perylene derivatives can be stimulated by the hypoxic tumor microenvironment to generate radical anion that is proposed to arouse electron exchange with oxidizing substance, and in turn, realize reactive oxygen species (ROS) burst.

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...
