Perylene diimides (PDI) are a well-studied class of functional organic dyes, and in recent years, they have been accepted as promising scaffolds for the design of small molecule/polymer-based chromogenic and fluorogenic reaction-based-probes because of their strong absorption combined with high fluorescence quantum yield in organic solvents, low reduction potential, good electron-acceptor properties, and broad color range properties.
Herein, a straightforward, sterically less demanding synthetic approach involving hybridization between two [6]helicene subunits and a perylene diimide (PDI) scaffold are presented, affording perylene diimide-embedded double [8]helicenes ( PD8Hs) which represent the highest double carbohelicenes reported thus far.

Cormier and Brian A. Gregg Our findings demonstrate that bromo substituents at the bay positions of perylene diimides are readily displaced under very mild conditions by potassium thioacetate resulting in the subject dithiane annulations. Herein, we report a hydrogen-bonding interfacial material, aliphatic amine-functionalized perylene-diimide (PDINN), which simultaneously down-shifts the work function of the air stable cathodes (silver and copper), and maintains good interfacial contact with the active layer. Thin films of nanocrystalline 3,4,9,10-perylene-tetracarboxylic-diimide (PTCDI) were prepared on quartz substrates by thermal evaporation technique. The structural properties were identified by transmission electron microscopy (TEM) and the X-ray diffraction (XRD).

Recently, much attention has been focused on their strong π-π stacks resulting from the large PDI aromatic core. These PDI stacks have distinct optical properties, and p Se hela listan på omlc.org We report here the preparation and use of perylene diimide derivative (PDI) with NIR absorbance (around 700 nm) as nanoprobes for tracking mesenchymal stromal cells (MSCs) in mice.

Due to the large conjugation and electron-deficient ability of perylene diimide, PDFC shows strong absorption, suitable energy levels and favorable face-on packing. The optimal device realizes a PCE of 12.56% with one of the highest fill factors (81.3%). A PCE of 9.66% is obtained in a 570 nm thick-film device based on PDFC.

In the report, two organic π‐conjugated molecules consisting of four perylene diimide (PDI) chromophores each are presented and used as non‐fullerene acceptors in indoor photovoltaic devices. The new materials consist of a dimeric N‐annulated PDI core with single PDIs grafted onto the pyrrolic N‐atom positions of the core.
