Phosphorescent perylene imides [PDF]

Chemical Communications, 2012
Asymmetrically substituted perylene imide derivatives PIa and PIx display phosphorescence in glassy matrices at 77 K. The lifetime is 49.0 ms for PIa and 13.5 ms for PIx. The triplet energy is 1.79 eV for PIa and 1.68 eV for PIx as confirmed by sensitization experiments of the C(60) triplet.

Panchromatic Light-Absorbing [70]Fullerene-Perylene-BODIPY Triad with Cascade of Energy Transfer as an Efficient Singlet Oxygen Sensitizer

Molecules, 2023
A panchromatic light-absorbing [70]fullerene-perylene-BODIPY triad (C70-P-B) was synthesized and applied as a heavy atom-free organic triplet photosensitizer for photooxidation. The photophysical processes were comprehensively investigated by the methods

Panchromatic Absorbers Tethered for Bioconjugation or Surface Attachment

Molecules, 2022
The syntheses of two triads are reported. Each triad is composed of two perylene-monoimides linked to a porphyrin via an ethyne unit, which bridges the perylene 9-position and a porphyrin 5- or 15-position.

Light-Harvesting Metal-Organic Frameworks (MOFs) La-PTC for Photocatalytic Dyes Degradation

Bulletin of Chemical Reaction Engineering & Catalysis, 2021
A novel porous metal organic framework, La-PTC was synthesized by solvothermal method using a perylene-3,4,9,10-tetracarboxylate ligand and lanthanum metal ion. The FTIR analysis showed that La-PTC has a different structure with PTCDA and Na4PTC.
