Photoinduced stepwise charge hopping in π-stacked perylene bisimide donor–bridge–acceptor arrays

open access: yesNature Chemistry
The mechanistic understanding of light-driven charge separation and charge-carrier transport within the frameworks of π-conjugated molecules is imperative to mimic natural photosynthesis and derive synthetic materials for solar energy conversion. In this

Liquid Crystalline Perylene Bisimide Derivatives Bearing Oligosiloxane Moieties

open access: yesChemistry
Perylene bisimide derivatives are typical n-type semiconductors as well as redox-active materials. However, it has been difficult to produce thin films by solution processes because of their low solubilities in organic solvents.

Size-dependent exciton dynamics in one-dimensional perylene bisimide aggregates

open access: yesNew Journal of Physics, 2012
The size-dependent exciton dynamics of one-dimensional aggregates of substituted perylene bisimides are studied by ultrafast transient absorption spectroscopy and kinetic Monte-Carlo simulations as a function of the excitation density and the temperature

Perylene-3,4:9,10-tetracarboxylic Acid Bisimide Dye as an Artificial DNA Base Surrogate

open access: yes, 2016
A phosphoramidite of the perylene bisimide dye was synthesized as a DNA building block that allows incorporation of this chromophore as an artificial nucleoside surrogate either at the 5‘-terminus or at internal positions of duplex DNA.

Switching or blinking? – The switching behaviour of single photochromic triads

open access: yesEPJ Web of Conferences, 2018
Photochromic molecules can be interconverted between two bistable conformations by light [1–3]. Irie and coworkers described a strategy to achieve superior fluorescence characteristics and outstanding switching characteristics of a photochromic unit by ...

Rational molecular design enhancing the photonic performance of red-emitting perylene bisimide dyes

open access: yes, 2017
We report the synthesis of novel multichromophoric organic architectures, where perylene red is decorated with BODIPY and/or hydroxycoumarin dyes acting as light harvesters and energy donors.

Substituent-dependent absorption and fluorescence properties of perylene bisimide radical anions and dianions.

open access: yesMaterials Horizons, 2021
Perylene-3,4:9,10-bis(dicarboximides) (PBIs) rank among the most important functional dyes and organic semiconductors, but only recently have their radical anions and dianions attracted interest for a variety of applications.

Ultrafast coherent exciton dynamics in size-controlled perylene bisimide aggregates

open access: yesStructural Dynamics, 2019
For H-aggregates of perylene bisimide (PBI), it has been reported that upon photoexcitation, an initially delocalized Frenkel exciton is localized by excimer formation.

Localized and Surface Plasmons Coupling for Ultrasensitive Dopamine Detection by means of SPR‐Based Perylene Bisimide/Au Nanostructures Thin Film

open access: yesAdvanced Materials Interfaces, 2021
Dopamine (DA) is an important catecholamine neurotransmitter involved in neural and hormonal functions. Neural diseases, as Parkinson's, are connected to a significant lowering of DA concentration to picomolar levels in cerebrospinal fluid.
