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.

Pyrene-substituted PDI were the most efficient singlet oxygen generator among the investigated photosensitizers with a 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-PDI) and pyrrolidine (Pyrr-PDI).

It is an organic heteropolycyclic compound and a dicarboximide. 2020-12-01 This study explores a new mode of contortion in perylene diimides where the molecule is bent, like a bow, along its long axis. These bowed PDIs were synthesized through a facile fourfold Suzuki macrocyclization with aromatic linkers and a tetraborylated perylene diimide … 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.

It is found in coal, oil and gas. This review discusses the important progress of perylene diimide (PDI)‐based polymers as non‐fullerene acceptors in all‐polymer solar cells (all‐PSCs) since 2014. The relationship between structure and property, matching aspects between donors and acceptors, and device fabrications are unveiled from a synthetic chemist perspective. Perylene diimide (PDI)-based small molecule is one of the most extensively investigated non-fullerene acceptors in recent years. This kind of n-type organic semiconductors holds many merits for photovoltaic devices, such as ease of synthesis and reproduction, high thermal and chemical stability, excellent electron-accepting ability and high electron mobility [27–30].

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.
