Two-Dimensional Molecular Network Built from Hierarchy Self-Assembly of Perylene Bisimide Derivatives.

ACS Applied Materials and Interfaces, 2021
The structures of two-dimensional (2D) self-assembled molecular networks formed by a series of perylene bisimide (PBI) derivatives were investigated by scanning tunneling microscopy (STM).

Application of a Near-Infrared Fluorescence Probe Based on Perylene Bisimide in the Detection of Heparin.

Langmuir
Heparin is widely used to treat thrombosis because it is an effective anticoagulant. However, excessive use of heparin can lead to an increased risk of bleeding, which makes the quantitative detection of heparin very important.

Energy Migration in Dendritic Oligothiophene-Perylene Bisimides

The Journal of Physical Chemistry B, 2012
A series of novel oligothiophene-perylene bisimide hybrid (DOTPBI) dendrimers up to the second generation (G0, G1, and G2) were investigated. Optical measurements such as nonlinear optical and time-resolved spectroscopy, including two-photon absorption, fluorescence upconversion, and excited state transient absorption were carried out. Results of these

A Perylene Bisimide Organogelator for Chlorinated Solvents

Asian Journal of Organic Chemistry, 2014
AbstractDye‐incorporated gel‐like materials are an attractive functional soft matter for optoelectronic applications. Chlorinated solvents are commonly used for the development of organic devices. Herein, we report that a perylene‐bisimide‐functionalized flexible bisurea can work as an efficient organogelator for several chlorinated solvents.

Localization/Delocalization of Charges in Bay‐Linked Perylene Bisimides

Chemistry – A European Journal, 2012
AbstractThe copper‐mediated Ullmann coupling of 1,7‐dibromoperylene bisimides afforded structurally perfect singly‐linked perylene bisimide (PBI) arrays, whilst the homo‐coupling of 1,12‐dibromoperylene bisimides gave doubly‐linked and triply‐linked diperylene bisimides.

Bay Region Borylation of Perylene Bisimides

European Journal of Organic Chemistry, 2011
AbstractNovel bispinacolborane‐N,N′‐bis(octyl)‐3,4,9,10‐perylenetetracarboxylic acid bisimide (PBI) was synthesized in high yield. The title compound is a key intermediate in the preparation of PBI aryl derivatives through Suzuki cross‐coupling by using a large variety of easily accessible aryl halides.

Fabrication of luminescent perylene bisimide nanorods

Journal of Luminescence, 2014
Abstract Perylene bisimides have attracted great interest as a result of their unique electrical and photophysical properties. In the present investigation a N,N′-bis(2-naphthalene-2-yl)perylene-3,4,9,10-tetracarboxylic diimide was synthesized from 2-aminonaphthalene and perylene-3,4,9,10-tetracarboxylic dianhydride.

Heterocyclic Annelated Di(perylene bisimide): Constructing Bowl-Shaped Perylene Bisimides by the Combination of Steric Congestion and Ring Strain

The Journal of Organic Chemistry, 2009
In this paper, we present the synthesis of S- and N-heterocyclic annelated di(perylene bisimide) with extraordinary doubly bowl-shaped structures. The structures of fused PBI bowls confirmed by single-crystal X-ray structure analysis and temperature-dependent (1)H NMR are realized by the introduction of the steric congestion in nonbay regions and by ...

Exciton Migration in Multistranded Perylene Bisimide J-Aggregates

The Journal of Physical Chemistry Letters, 2020
Exciton 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 ...

Perylene bisimide J-aggregates with absorption maxima in the NIR

Chemical Communications, 2008
NIR absorbing J-aggregates with biomimetic features of chlorophyll dye assemblies are obtained upon hydrogen-bond directed self-assembly of a green 1,7-diamino-substituted perylene bisimide dye.
