One-Dimensional Exciton Diffusion in Perylene Bisimide Aggregates
The Journal of Physical Chemistry A, 2010The dynamics and mobility of excitons in J-aggregates of perylene bisimides are investigated by transient absorption spectroscopy with a time resolution of 50 fs. The transient spectra are compatible with an exciton delocalization length of two monomers and indicate that vibrational and configurational relaxation processes are not relevant for the ...

Ambient Stable Zwitterionic Perylene Bisimide‐Centered Radical
Angewandte Chemie, 2014AbstractThe unexpected introduction of a cationic imidazolium substituent in the 2‐position of a tetrachloro‐substituted perylene‐3,4:9,10‐tetracarboxylic acid bisimide (PBI) by the reaction of PBI‐Cl41with the N‐heterocyclic carbene 1,3‐di‐iso‐propyl‐imidazolin‐2‐ylidene (iPr2Im2) enables the isolation of an ambient stable zwitterionic radical.

Perylene Bisimide Atropisomers: Synthesis, Resolution, and Stereochemical Assignment
The Journal of Organic Chemistry, 2007The macrocyclization of the tetra-hydroxyphenoxy-substituted perylene bisimide 4 bearing two (R)-configured 2-octyl substituents in the imide positions by etherification with diethylene glycol ditosylate afforded both the diagonally bridged (1,7- and 6,12-linkage) and laterally bridged (1,12- and 6,7-linkage) regioisomers 6 and 7.

Perylene Bisimide Radicals and Biradicals: Synthesis and Molecular Properties
Angewandte Chemie International Edition, 2015AbstractUnprecedented neutral perylene‐3,4:9,10‐tetracarboxylic acid bisimide (PBI) radicals and biradicals were synthesized by facile chemical oxidation of 4‐hydroxyaryl‐substituted PBIs. Subsequent characterization by optical and magnetic spectroscopic techniques, as well as quantum chemical calculations, revealed an open‐shell singlet biradical ...

Assembly of DNA Triangles Mediated by Perylene Bisimide Caps
Chemistry – A European Journal, 2011AbstractPerylene bisimides (PBI) have been synthetically incorporated as caps onto a Y‐shaped DNA triple strand. These PBI caps serve as “sticky” ends in the spontaneous assembly of larger DNA ensembles, linking the triangular DNA through stacking interactions.

Synthesis and electropolymerization of novel oligothiophene-functionalized perylene bisimides
Chem. Commun., 2004Fourfold oligothiophene-functionalized perylene bisimides have been synthesized by esterification of hydroxyphenoxy-substituted perylene bisimides and their optical properties as well as electrochemical polymerization properties have been investigated.
