Ultrafast Symmetry-Breaking Charge Separation in a Perylene Bisimide Dimer Enabled by Vibronic Coupling and Breakdown of Adiabaticity.

Journal of the American Chemical Society, 2022
Perylene bisimides (PBIs) have received great attention in their applicability to optoelectronics. Especially, symmetry-breaking charge separation (SB-CS) in PBIs has been investigated to mimic the efficient light capturing and charge generation in ...

Calixarene-induced aggregation of perylene bisimides

Org. Biomol. Chem., 2012
The complex-induced aggregation of perylene bisimides by p-sulfonatocalix[n]arenes was studied, where the aggregation stability, aggregation distance, as well as the degree of order of aggregation were all improved.

Perylene Bisimide Cyclophanes as Biaryl Enantiomerization Catalysts─Explorations into π-π Catalysis and Host-Guest Chirality Transfer.

Journal of Organic Chemistry, 2022
The racemization of axially chiral biaryls is a fundamental step toward transforming kinetic resolutions into dynamic kinetic resolutions (DKRs). The high enantiomerization barriers of many biaryl compounds of synthetic relevance, however, may render DKR

Light-Controlled Switching of Perylene Bisimide Assemblies

The Journal of Physical Chemistry Letters, 2023
Light-driven changes in supramolecular interactions in perylene bisimides (PBIs) with pendant sulfur-containing functional groups at the bay position are demonstrated. In the ground state, a noncovalent S···X interaction between the σ-hole on sulfur and a heteroatom, X (X = O, N, S), of a neighboring molecule is the main driving force for ...

Molecular Assemblies of Perylene Bisimide Dyes in Water

Angewandte Chemie - International Edition, 2012
AbstractPerylene bisimides are among the most valuable functional dyes and have numerous potential applications. As a result of their chemical robustness, photostability, and outstanding optical and electronic properties, these dyes have been applied as pigments, fluorescence sensors, and n‐semiconductors in organic electronics and photovoltaics ...

Perylene bisimide J-aggregates in polymer matrix: controlling self-assembly and fluorescence properties

Journal of Materials Chemistry C
Perylene bisimide J-aggregates are among the most emissive dye aggregates. However, their fluorescence quantum yield severely decreases if casted as pristine materials in solid films.

Photoinduced Cascading Charge Transfer in Perylene Bisimide-Based Triads.

Journal of Physical Chemistry B, 2022
We synthesize three perylene bisimide-based triads with donor-acceptor-acceptor (D∼A1-A2) architectures, in which the distance between D and A1 is varied to study its influence on the excited state electron processes. Very different intramolecular charge
