“Helter‐Skelter‐Like” Perylene Polyisocyanopeptides

Chemistry – A European Journal, 2009
AbstractExciton migration! Spectroscopic analyses and extensive molecular dynamics studies revealed a well‐defined 41 helix in which the perylene molecules (see figure) form four “helter‐skelter‐like” overlapping pathways along which excitons and electrons can rapidly migrate.magnified imageWe report on a combined experimental and computational ...

Perylene−Tetrapalladium Sandwich Complexes

Journal of the American Chemical Society, 2003
Bis-perylene-tetrapalladium sandwich complexes are synthesized and structurally characterized. These are the first examples of bis-arene sandwich complexes having metal-metal bond chains. X-ray crystallographic analyses showed that the tetrapalladium chain is bound to perylene ligands at the C8 edge position.

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.

Hybrid Tetrameric Perylene Diimide Assemblies

ChemSusChem, 2021
AbstractOrganic photovoltaics have found utility as indoor light recycling devices providing an opportunity for the sustainable powering of IoT sensors and related smart electronics. In the report, two organic π‐conjugated molecules consisting of four perylene diimide (PDI) chromophores each are presented and used as non‐fullerene acceptors in indoor ...

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.

Self-Organized Perylene Diimide Nanofibers

The Journal of Physical Chemistry B, 2004
A propeller-shaped perylene diimide trimer was synthesized and a simple evaporation method was used for the self-organization of trimer molecules into fluorescent nanofibers. The sizes of these fibers-from 4 to 150 nm in diameter-were measured by atomic force microscopy and can be controlled by adjusting the concentration of the initial solution.

Perylene, Oligorylenes, and Aza-Analogs

ACS Applied Materials & Interfaces, 2015
An in-depth discussion of the properties of perylene is presented. Tuning the properties of perylene by introducing nitrogens is also explored. Finally, we do not discuss the synthesis and properties of oligorylenes functionalized with dicarboxyimide bonds.

Perylene‐ and Perylene Diimide‐based Framework Materials Constructed through Metal Coordination

Chemistry – A European Journal
AbstractMetal‐organic frameworks (MOFs) are a class of materials composed of coordinative interactions between metal ions and organic linkers, encompassing two‐dimensional (2D), and three‐dimensional (3D) architectures. Metal‐organic cages (MOCs), a special case of these species, are discrete molecular “capsules” with zero‐dimensional (0D) structures ...

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.
