Gelation of a Highly Fluorescent Urea-Functionalized Perylene Bisimide Dye

, 2016
A urea-containing tetraphenoxy-substituted perylene bisimide has been synthesized, and its gelation ability has been studied. This functional dye forms fluorescent organogels in toluene and tetrachloromethane through self-assembly by hydrogen-bonding and

Solvent mediated intromolecular photoinduced electron transfer in a fluorene-perylene bisimide derivative

, 2006
Photoinduced electron transfer from fluorene to perylene bisimide has been studied for 2,7-bis(N-(1-hexylheptyl)-3,4:9,10-perylene-bisimide-N'-yl))-9,9-didodecylfluorene (PFP) in 11 different organic solvents. The intramolecular charge-separated state in

Preparation and Characterization of Regioisomerically Pure 1,7-Disubstituted Perylene Bisimide Dyes

, 2016
A detailed study on bromination and subsequent imidization of perylene bisanhydride with cyclohexylamine is reported. The present results reveal that previously reported 1,7-difunctionalized perylene bisimides are presumably contaminated with the ...

Tetraphenylethene modified perylene bisimide: effect of the number of substituents on AIE performance

, 2012
Perylene bisimide derivatives substituted with one and two tetraphenylethene moieties at 1 and 1,7-postions show distinct optical properties. The former displays characteristic emission features of perylene bisimides in solution and red emission in the ...

Multichromophoric perylene bisimide dyes

, 2009
ABSTRACT: Chromophores are responsible for the color of matter. The control of molecular interactions in multichromophores lead to functional dyes with novel properties. Furthermore, tailormade spectroscopic properties could be achieved, which are a prerequisite for applications that require dyes with absorption and emission in a specific region of the
