Altering singlet fission pathways in perylene-dimers; perylene-diimide versus perylene-monoimide

Nanoscale, 2022
The inherent differences on coplanarity and dipole moment in perylene-monoimides versus perylene-diimides and their impact on the singlet fission process were investigated in a series of phenylene- and naphthalene-linked dimers.

Self‐Assembling Behaviour of Perylene, Perylene Diimide, and Thionated Perylene Diimide Deciphered through Non‐Covalent Interactions

ChemPhysChem, 2022
AbstractThe π‐conjugated supramolecular polymers (SMP) have gained vast popularity in materials chemistry and biomedicine due to their spectacular self‐assembling behaviour. A detailed account of the electronic structure and bonding through quantum theory of atoms‐in‐molecules, non‐covalent interactions, and energy decomposition analysis (EDA) in the ...

Positron mobility in perylene

Physical Review B, 1993
Based on Doppler-shift measurements we have determined the positron drift velocity u in a high-purity monoclinic \ensuremath{\alpha}-perylene single crystal as a function of applied electric field F and temperature. The electric field is applied as a triangular wave with a maximum field ${\mathit{F}}_{\mathrm{max}}$.

Fusing perylene diimide with helicenes

Chirality, 2023
AbstractIncorporating perylene diimide (PDI) units into helicene structures has become a useful strategy for giving access to non‐planar electron acceptors as well as a method of creating molecules with unique and intriguing chiroptical properties. This minireview describes this fusion of PDIs with helicenes.

Grafting Perylenes to ZnO Nanoparticles

Chemistry – A European Journal, 2014
AbstractA new prototype of dendritic perylenes suitable for the chemical functionalization of inorganic nanoparticles was synthesized and characterized. The bay‐functionalized perylene core of these molecular architectures was coupled to a catechol moiety, which serves as an anchor group for the functionalization of metal oxides, in particular ZnO.

Thermochromism of perylenes: Dynamics in aromatics

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2011
A thermal equilibrium between planar and skew perylene derivatives induces thermochromism and may modulate molecular recognition. Thus, the long-lasting discussion about the geometry of perylene could be solved in terms of this equilibrium. Extension to other aromatics and practical applications such as for non contact fluorescence thermometers are ...

Perylene and Perylene-Derivative Nano-Cocrystals: Preparation and Physicochemical Property

Japanese Journal of Applied Physics, 2012
Organic nano-cocrystals of functional dyes of perylene and a perylene derivative were successfully prepared by the reprecipitation method. The particle sizes, optical properties, and powder X-ray diffraction patterns of nano-cocrystals were evaluated.

Highly Fluorescent Platinum(II) Organometallic Complexes of Perylene and Perylene Monoimide, with Pt σ-Bonded Directly to the Perylene Core

Inorganic Chemistry, 2010
3-Bromoperylene (BrPer) or N-(2,5-di-tert-butylphenyl)-9-bromo-perylene-3,4-dicarboximide (BrPMI) react with [Pt(PEt(3))(4)] to yield trans-[PtR(PEt(3))(2)Br] (R = Per, 1a; R = PMI, 1b). Neutral and cationic perylenyl complexes containing a Pt(PEt(3))X group have been prepared from 1a,b by substitution of the Br ligand by a variety of other ligands ...

Novel perylene‐containing polymers [PDF]

Macromolecular Chemistry and Physics, 1996
AbstractNovel perylene‐containing polymers have been synthesized. They exhibit good solubilities in organic solvents and have good film forming properties. A water‐soluble perylene‐containing polyimide was obtained via sulfonation of the corresponding polyimide.
