Regioselective ortho-π-extention of a perylene diimide (PDI) core with four fused heteroaromatics leads to the formation a special PDI double-[7]heterohelicene, which both inherits a high dissymmetry factor from the helicene skeleton and maintains an outstanding charge transport ability from the …

These results revealed that perylene diimide supramolecular photocatalyst may be efficiently applied for the remediation of tetracycline contaminated natural waters. SEM (a, c) and TEM (b, d

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. Herein, we used perylene diimide (PDI), naphthalene diimide (NDI), and naphthodithiophene diimide (NDTI) with the same alkyl chains combined with dithienothiophene (DTT) unit to obtain three polymer acceptors PPDI-DTT, PNDI-DTT, and PNDTI-DTT, respectively. 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. IDENTIFICATION: Perylene is a yellow to colorless crystalline or plate-like solid.

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. 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.

Bis-Dithiano Perylene Diimide: Synthesis and Characterization of a Novel Ring System Russell A. 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.

The synthesis was taken from "Synthesis, Self-Assembly, and Solar Cell Performance o 2013-04-21 Abstract: Perylene tetracarboxylic diimide (PTCDI), derivatives have attracted the attention of the scientific community owing to their thermal stability, electron affinity-enabling n-type semiconductor behaviour and useful photophysical properties.Thin films of six new perylene tetracarboxylic diimides were fabricated on glass substrate by spin coating. Perylene diimide synthesis Scheme 1 contains the three perylene diimides (PDIs) surveyed in this study. Each chromophore is based on a di-bromo PDI that has been substituted in the bay positions of the perylene core with p-(t-butyl)phenol (PhO-PDI), dodecanethiol (Thiol- 2014-03-05 (2007). Perylene Diimide–Oligonucleotide Conjugates Constructed by Click Chemistry.

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 The fluorescence emission spectrum of Perylene-diimide, [PDI] dissolved in toluene.
