Highly Regiospecific Synthetic Approach to Monobay-Functionalized Perylene Bisimide and Di(perylene bisimide)

Organic Letters, 2009
Monobay-dichlorinated perylene bisimide and diperylene bisimide have been regiospecifically synthesized from tetrachlorinated perylene bisimide in different copper-mediated reaction conditions, thus opening a new avenue to their monobay-functionalization.

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.

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 ...

Aggregation Processes of Perylene Bisimide Diimidazolium Salts

Chemistry – A European Journal, 2015
AbstractThe supramolecular aggregation of three diimidazolium‐functionalized perylene bisimides, differing in the alkyl chain length was investigated. These salts form aggregates in solvents like chloroform, dichloromethane, and glycerol. Solvent‐, concentration‐, and temperature‐dependent spectroscopic studies were carried out, evidencing the ...

Twisted, Z-Shaped Perylene Bisimide

Journal of the American Chemical Society, 2005
The 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 ...

Iridium-Catalyzed Direct Tetraborylation of Perylene Bisimides

Organic Letters, 2011
Treatment of perylene bisimides (PBIs) with bis(pinacolato)diboron in the presence of an iridium catalyst provides tetraborylated PBIs at 2,5,8,11-positions in good yields with perfect regioselectivity. The planar structure of the perylene core has been confirmed by X-ray diffraction analysis.

Anthraceno-Perylene Bisimides: The Precursor of a New Acene

Organic Letters, 2011
A controlled synthesis strategy for a anthracene-fused perylene bisimide was developed from the cyclization of an anthracene unit pendant to a perylene diimide scaffold. The direct cyclization led to a zigzag molecule, while a Diels-Alder strategy influenced the regiochemistry of cyclization to afford the linear precursor of a new acene.
