Passivierung von Defektzuständen in organischen n‐Typ‐Ladungstransferkomplexen durch molekularen Sauerstoff

Angewandte Chemie, EarlyView.
O2 verbessert den Ladungstransfer in organischen n‐Typ‐Donor‐Akzeptor‐Ladungstransferkomplexen (CTCs) durch physisorptive Passivierung von Ladungsträgerfallen. Durch die Unterdrückung der Rekombination und die Förderung langlebiger delokalisierter Ladungsträger verbessert O2 den Elektronentransport und die Leitfähigkeit ohne Dotierung.

A study of the elemental reactions involved in the initiation of the polymerization of tetrahydrofuran induced by the photosensitization of a triphenylsulphonium salt by perylene

Journal of the Brazilian Chemical Society, 2003
The photopolymerization of THF was studied in the presence of a triphenylsulphonium salt and perylene. The mechanism involves an electron transfer from the excited singlet state of perylene to triphenylsulphonium ions, resulting in perylene cation ...

Perylene-Based Fluorescent Nanoprobe for Acid-Enhanced Detection of Formaldehyde in Lysosome

, 2018
Formaldehyde (FA), as a reactive carbonyl species, is extremely hazardous to human health if its concentration is above normal level. In live cells, lysosome is a main organelle to generate endogenous FA. Thus, the design of facile, stable, and sensitive

Molecular Organization Induced Anisotropic Properties of Perylene – Silica Hybrid Nanoparticles

Scientific Reports, 2017
Optically active silica nanoparticles are interesting owing to high stability and easy accessibility. Unlike previous reports on dye loaded silica particles, here we address an important question on how optical properties are dependent on the aggregation-

Molecular Dioxygen‐Mediated Passivation of Electron Traps in n‐Type Organic Charge‐Transfer Complexes

Angewandte Chemie International Edition, EarlyView.
O2 enhances charge‐transfer in n‐type organic donor–acceptor charge‐transfer complexes (CTCs) via physisorption‐mediated trap passivation. By suppressing recombination and promoting long‐lived delocalized charge carriers, O2 improves electron transport and conductivity without doping.

Liquid Crystalline Perylene Bisimide Derivatives Bearing Oligosiloxane Moieties

Chemistry
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.

Photoinduced Electron Transfer (PET) as Key to Accelerate the Cycloreversion Reaction of Arylquadricyclanes

Chemistry – A European Journal, EarlyView.
It is demonstrated that the photoinduced cycloreversion of a methoxynaphthylquadricyclane in the presence of suitable photocatalysts gives quantitatively the corresponding norbornadiene. As this photochromic norbornadiene‐quadricyclane cycle has favorable properties for light energy conversion, this method provides a useful tool for the targeted ...
