Perylene Bisimide Cyclophanes: Structure–Property Relationships upon Variation of the Cavity Size

Organic Materials, 2020
Five cyclophanes composed of two perylene bisimide (PBI) dyes and various CH2–arylene–CH2 linker units were synthesized. PM6-D3H4 geometry-optimized structures and a single crystal for one of these cyclophanes reveal well-defined distances between the ...

Transient Optical Characterisation of Donor-Acceptor Block Copolymers for Use in Solar Cells [PDF]

, 2010
This thesis presents a study of photo-active, semiconducting block copolymers for use in molecular solar cells. Current state-of-the-art organic devices utilise blends of two (or more) materials that are co-deposited from a common solution; the resulting

Reversible Photoreduction as a Trigger for Photoresponsive Gels [PDF]

, 2016
We present here a new type of photoresponsive, reversible low molecular weight gel. All previous examples rely on a photoisomerisation, ring-closing or dimerization. We show that photoreduction of a perylene bisimide gelator results in the formation of a

Fused‐ring induced end‐on orientation in conjugated molecular dyads toward efficient single‐component organic solar cells

Aggregate, 2023
The molecular orientations of conjugated materials on the substrate mainly include edge‐on, face‐on, and end‐on. Edge‐on and face‐on orientations have been widely observed, while end‐on orientation has been rarely reported.

Controlled aggregation of peptide-substituted perylene-bisimides [PDF]

Chemical Communications, 2012
Controlled aggregation of perylene bisimides in multiple modes has been achieved via symmetric substitution with peptides. Using optical probes of aggregation, the balance of hydrophobic and electrostatic forces are found to play a key role in directing self assembly and are exploited via solvent, pH, and specific extrinsic ion effects.

A supramolecular helix that disregards chirality [PDF]

, 2016
The functions of complex crystalline systems derived from supramolecular biological and non-biological assemblies typically emerge from homochiral programmed primary structures via first principles involving secondary, tertiary and quaternary structures.

Iridium-Catalyzed Direct Tetraborylation of Perylene Bisimides [PDF]

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.

Discrete Dimers of Redox-Active and Fluorescent Perylene Diimide-Based Rigid Isosceles Triangles in the Solid State [PDF]

, 2019
The development of rigid covalent chiroptical organic materials, with multiple, readily available redox states, which exhibit high photoluminescence, is of particular importance in relation to both organic electronics and photonics. The chemically stable,

Pi‐Stacking Enhances Stability, Scalability of Formation, Control over Flexibility, and Circulation Time of Polymeric Filamentous Nanocarriers

Advanced NanoBiomed Research, 2021
Self‐assembling filomicelles (FMs) are of great interest to nanomedicine due to their structural flexibility, extensive systemic circulation time, and amenability to unique “cylinder‐to‐sphere” morphological transitions.
