Self-sorted Oligophenylvinylene and Perylene Bisimide Hydrogels [PDF]

open access: yesScientific Reports, 2017
We describe two component hydrogels with networks composed of self-sorted fibres. The component gelators are based on 1,4-distyrylbenzene (OPV3) and perylene bisimide (PBI) units.

Photothermal Perylene Bisimide Hydrogels. [PDF]

open access: yesChemistry, 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

Mechanoresponsive Self-Assembled Perylene Bisimide Films. [PDF]

open access: yesChemistry, 2020
AbstractIn this work, self‐assembled amino‐acid appended perylene bisimides (PBIs) have been studied that when processed into thin films change their resistivity in response to being bent. The PBIs assemble into structures in water and form thin films upon drying.

Globular Aggregates Stemming from the Self-Assembly of an Amphiphilic N-Annulated Perylene Bisimide in Aqueous Media [PDF]

open access: yesNanomaterials, 2021
Herein, we describe the synthesis of highly emissive amphiphilic N-annulated PBI 1 decorated with oligo ethylene glycol (OEG) side chains. These polar side chains allow the straightforward solubility of 1 in solvents of different polarity such as water ...

Supramolecular Chiral Discrimination of D-Phenylalanine Amino Acid Based on a Perylene Bisimide Derivative [PDF]

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
The interaction between homochiral substituted perylene bisimide (PBI) molecule and the D enantiomer of phenylalanine amino acid was monitored. Spectroscopic transitions of PBI derivative in aqueous solution in the visible range were used to evaluate the

Antifungal Activity of Amphiphilic Perylene Bisimides

open access: yesMolecules, 2022
Perylene-based compounds, either naturally occurring or synthetic, have shown interesting biological activities. In this study, we report on the broad-spectrum antifungal properties of two lead amphiphilic perylene bisimides, compounds 4 and 5, which ...

Ultrafast coherent exciton dynamics in size-controlled perylene bisimide aggregates [PDF]

open access: yesStructural Dynamics, 2019
For H-aggregates of perylene bisimide (PBI), it has been reported that upon photoexcitation, an initially delocalized Frenkel exciton is localized by excimer formation.

Nanostructured polyurethane perylene bisimide ester assemblies with tuneable morphology and enhanced stability [PDF]

open access: yesRoyal Society Open Science, 2018
Size control has been successfully achieved in inorganic materials, but it remains a challenge in polymer nanomaterials due to their polydispersity. Here, we report a facile approach to tailor the diameters of polyurethane (PU) nanoparticles (490 nm, 820
