Effect of structural bending on the photophysical properties of perylene bisimide.
Journal of Chemical PhysicsThe effect of nonplanarity on the electronic properties of π-systems has been difficult to study systematically because of the limited availability of suitable model compounds. Our group recently synthesized a series of end-to-end bent perylene bisimide (

Perylene Bisimide-Based Luminescent Liquid Crystals with Tunable Solid-State Light Emission.
ACS Applied Materials and Interfaces, 2021Perylene bisimides are among the most studied building blocks for supramolecular assemblies in the fabrication of optoelectronic devices for their exceptional optical and electronic properties; however, developing perylene bisimide-based luminescent ...

The singlet fission (SF) process is generally defined as the conversion of one singlet exciton (S1) into two triplet excitons (2·T1), which has the potential to overcome thermalization losses in the field of photovoltaic devices. Given the limitations of

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.

Cooperative Binding and Chirogenesis in an Expanded Perylene Bisimide Cyclophane.
Journal of the American Chemical SocietyThe encapsulation of more than one guest molecule into a synthetic cavity is a highly desirable yet a highly challenging task to achieve for neutral supramolecular hosts in organic media.

Aggregation Processes of Perylene Bisimide Diimidazolium Salts
Chemistry – A European Journal, 2015AbstractThe 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 ...

Exciton Migration in Multistranded Perylene Bisimide J-Aggregates
The Journal of Physical Chemistry Letters, 2020Exciton migration in self-assembled supramolecular ensembles of dye molecules is controlled by the electronic coupling between adjacent sites, the delocalization of the excitation and thereby by the packing arrangement. Here, we put emphasis on the packing structure and analyze the exciton migration in two perylene bisimide-based J-aggregates composed ...
