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

open access: yes, 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 ...

Relaxation dynamics of higher excited states of perylene-substituted perylene bisimide derivatives

open access: yesThe Journal of Chemical Physics
Stepwise two-photon absorption processes have received considerable attention, especially in photocatalysis, due to their relatively lower power threshold, characteristic spatial selectivity, amplification of chemical reactions, and so on. Meanwhile, studies on the relaxation dynamics of higher excited states in condensed systems have been limited for ...

Multichromophoric perylene bisimide dyes

open access: yes, 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

AIEE active perylene bisimide supported mercury nanoparticles for synthesis of amides via aldoximes/ketoximes rearrangement

open access: yes, 2015
Aggregates of perylene bisimide (PBI) derivative 3 serve as reactors and stabilizers for the preparation of mercury nanoparticles (HgNPs) which exhibit excellent catalytic efficiency in the conversion of aldoximes/ketoximes into primary/secondary amides ...
