Light‐Driven Charge Separation in Isoxazolidine–Perylene Bisimide Dyads

Chemistry – A European Journal, 2009
AbstractA series of arrays for light‐driven charge separation is presented, in which perylene tetracarboxylic bisimide is the light‐absorbing chromophore and electron acceptor, whereas isoxazolidines are colourless electron donors, the electron‐releasing properties of which are increased with respect to the amino group by means of the α‐effect.

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 ...

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.

Asymmetric perylene bisimide dyes with strong solvatofluorism

Dyes and Pigments, 2013
Abstract Two asymmetric perylene bisimide dyes, 1-cyano-7-piperidinylperylene bisimide ( 1 ) and 1-bromo-7-piperidinylperylene bisimide ( 2 ), were synthesized and fully characterized. These molecules undergo an excited-state intramolecular electron transfer reaction, resulting in a unique charge transfer emission, of which the peak wavelength ...
