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

Twisted, Z-Shaped Perylene Bisimide
Journal of the American Chemical Society, 2005The first derivative of a new class of perylene bisimide chromophores, N,N'-bis(octyl)-3,9-bis(phenyl)perylene-1,2,7,8-tetracarboxyl bisimide, 1, has been synthesized and its fundamental photophysical and electrochemical properties assessed. The extended, Z-shaped structure was achieved by use of the classic photoenolization of an o-methylbenzophenone ...

Light-Controlled Switching of Perylene Bisimide Assemblies
The Journal of Physical Chemistry Letters, 2023Light-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 ...

Calixarene-induced aggregation of perylene bisimides
Org. Biomol. Chem., 2012The 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.

Photoinduced Cascading Charge Transfer in Perylene Bisimide-Based Triads.
Journal of Physical Chemistry B, 2022We 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

Photoluminescence of Self‐organized Perylene Bisimide Polymers
Macromolecular Chemistry and Physics, 2004AbstractSummary: 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
