Tuning the Electronic Structure and Properties of Perylene–Porphyrin–Perylene Panchromatic Absorbers

The Journal of Physical Chemistry A, 2016
Light-harvesting architectures that afford strong absorption across the near-ultraviolet to near-infrared region, namely, panchromatic absorptivity, are potentially valuable for capturing the broad spectral distribution of sunlight. One previously reported triad consisting of two perylene monoimides strongly coupled to a free base porphyrin via ethyne ...

D–A Type Perylene Micelles With Synergistic Charge/Energy Transfer for Dual‐Path ROS Generation and Enhanced Photocatalysis

Advanced Science, EarlyView.
Dual‐state activation of singlet and triplet excitons is achieved in perylene‐based nanomicelles via donor engineering. By synergistically pairing charge transfer with energy transfer pathways, while concurrently enabling pollutant pre‐enrichment, this strategy establishes spatial coupling between efficient ROS generation and rapid mineralization ...

Dissipative Regenerative Chemiluminescence in Water: A Perylene‐Based Out‐of‐Equilibrium Light‐Emitting System

Angewandte Chemie, EarlyView.
Driven by sodium dithionite and hydrogen peroxide under mild aqueous conditions, a water‐soluble perylene bisimide undergoes reversible electron‐transfer cycles that generate its emissive excited state without dye decomposition. We define this out‐of‐equilibrium system as chemically fueled regenerative chemiluminescence (CFRCL), opening new avenues for

N-Annulated Perylene Diimide Non-Fullerene Acceptors for Organic Photovoltaics

Colorants, 2023
This work covers the development of non-fullerene acceptors for use in organic photovoltaics built using the N-annulated perylene diimide dye. The classic perylene diimide dye has been extensively used to construct non-fullerene acceptors, leading to ...

Local Solvent Ordering Drives Supramolecular Chirality Inversion

Advanced Science, EarlyView.
Local solvent organization is shown to govern supramolecular chirality by selecting distinct chiral assembly pathways. A subtle change in water‐DMSO composition reverses the helical sense of a chiral perylene bisimide, while heating induces an irreversible thermal inversion to a more stable enantiomorph.

Facile Synthesis of Dicyclohepta[cd,fg]‐as‐indacene and Confirmation of its Anti‐Kasha S3 Emission

ChemistryEurope
Interest in non‐benzenoid polycyclic aromatic hydrocarbons (PAHs) has rapidly increased due to their unique electronic configurations and physical properties, which differ significantly from those of their benzenoid counterparts.

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).

Engineering Ultrastable Intrinsic Radicals: Graphene Quantum Dots With NIR‐II Emission for Dynamic Deep‐Tissue Bioimaging

Advanced Science, EarlyView.
Stable radicals are attractive for photonic and quantum information technologies but are often limited by instability. We stabilize intrinsic radicals in graphene quantum dots via 2D polymerization of perylene derivatives, where bilayer defect confinement suppresses quenching (100–500 K).

Investigation on Fluorescence Quenching Mechanism of Perylene Diimide Dyes by Graphene Oxide

Molecules, 2016
Perylene diimide derivatives were used as probes to investigate the effect of the molecular structures on the fluorescence quenching mechanism in a perylene diimide/graphene oxide system.

Chemical Bond‐Orchestrated Energy Depletion to Augment Lung Cancer Chemo‐Immunotherapy

Advanced Science, EarlyView.
This study grafted dichloroacetic acid (DCA) into perylenediimide (PDI) skeleton via ionic or covalent bond to create novel metabolic agent PDIC‐AC and PDIC‐NAC, explicitly elaborated the underlying energy metabolism and therapeutic mechanism, and developed a promising strategy for energy metabolism‐targeting chemo‐immunotherapy by chemical bond ...
