Effect of benzocyclobutadieno-annelation on cyclic conjugation in perylene

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2011
Earlier studies showed that the intensity of cyclic conjugation in the central ring R of perylene can be significantly altered by means of benzo-annelation. In particular, linear (resp. angular) benzoannelation was found to decrease (resp.

Novel Perylene Derivatives as Highly Photostable Fluorescent Dyes

open access: yesCHIMIA, 1994
Perylene-3,4-dicarboxylic imides are prepared by a new decarboxylizing condensation with moderately sterically hindered primary amines. Perylene-3,4-dicarboxylic anhydride is prepared via a saponification reaction of the dicarboximide and is a ...

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

open access: yesMolecules, 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

Effect of molecular and electronic structure on the light harvesting properties of dye sensitizers [PDF]

open access: yes, 2007
The systematic trends in structural and electronic properties of perylene diimide (PDI) derived dye molecules have been investigated by DFT calculations based on projector augmented wave (PAW) method including gradient corrected exchange-correlation ...

Spectroscopy of PTCDA attached to rare gas samples: clusters vs. bulk matrices. I. Absorption spectroscopy [PDF]

open access: yes, 2012
The interaction between PTCDA (3,4,9,10-perylene-tetracarboxylic-dianhydride) and rare gas or para-hydrogen samples is studied by means of laser-induced fluorescence excitation spectroscopy.

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

open access: yesAdvanced 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.

Exploring Optically Fueled Dissipative Self-Assembly of a Redox-Active Perylene Diimide Scaffold

open access: yesOrganic Materials, 2022
Dissipative self-assembly is ubiquitous in nature and underlies many complex structures and functions in natural systems. These processes are primarily enabled by the consumption of chemical fuels.

Transient Optical Characterisation of Donor-Acceptor Block Copolymers for Use in Solar Cells [PDF]

open access: yes, 2010
This thesis presents a study of photo-active, semiconducting block copolymers for use in molecular solar cells. Current state-of-the-art organic devices utilise blends of two (or more) materials that are co-deposited from a common solution; the resulting

Fluorofluorescent Perylene Bisimides [PDF]

open access: yesSynlett, 2018
Perfluorinated liquids can exhibit immiscibility with organic solvents and water, and provide orthogonal opportunities in chemistry. Examples of emissive dyes that display only fluorous phase solubility are limited, despite the many potential applications.
