Photothermal Perylene Bisimide Hydrogels. [PDF]
Chemistry, 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

Dinaphthothiepine Bisimide and Its Sulfoxide: Soluble Precursors for Perylene Bisimide [PDF]
Journal of the American Chemical Society, 2020 The synthesis and properties of dinaphtho[1,8-bc:1',8'-ef]thiepine bisimide (DNTBI) and its oxides are described. Their molecular design is conceptually based on the insertion of a sulfur atom into the perylene bisimide (PBI) core. These sulfur-inserted PBI derivatives adopt nonplanar structures, which significantly increases their solubility in common

Antifungal Activity of Amphiphilic Perylene Bisimides
Molecules, 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 ...

Observation of Two-Exciton States in Perylene Bisimide Aggregates
EPJ Web of Conferences, 2013 The behavior of excitons on perylene bisimide aggregates is investigated at high excitation densities by femtosecond absorption spectroscopy. Indications for a significant population in the two-exciton manifold are found.

Photoluminescence of Self‐organized Perylene Bisimide Polymers
Macromolecular Chemistry and Physics, 2004 AbstractSummary: Three polymers consisting of alternating perylene bisimide chromophores and flexible polytetrahydrofuran segments of different length have been studied using absorption and (time‐resolved) photoluminescence spectroscopy. In o‐dichlorobenzene, the chromophores self organize to form H‐like aggregates. The photoluminescence spectra of the

Mechanoresponsive Self-Assembled Perylene Bisimide Films. [PDF]
Chemistry, 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.

Fluorofluorescent Perylene Bisimides [PDF]
Synlett, 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.

Switch of dimensionality of exciton diffusion in aggregates [PDF]
EPJ Web of Conferences, 2019 The ultrafast exciton dynamics in J-aggregates of a perylene bisimide dye is investigated for temperatures down to 77 K revealing at low temperatures a decrease of the exciton mobility and a change in the dimensionality.
