2021年9月1日 · Our group successfully deposited well-dispersed Pt QDs (quantum dots) on PDI supramolecular nanorods via a mild and in situ chemical reduction (Fig. 10 a), and the optimum 1 wt.% Pt QDs/PDI composite showed remarkably enhanced photocatalytic performance with phenol degradation rate 6.2 times higher than pure PDI supramolecular nanorods under ...

The consecutive photoexcitation of perylene diimide (PDI) produces the excited doublet state of its radical anion (PDI˙−*), which is demonstrated to be a strong photoreductant for difficult-to-reduce substrates, such as aryl halides.

2023年4月24日 · In this work, a facile and straightforward method has been developed to control the doping of perylene diimide to create radical anions using organic polymer polyethyleneimine (PEI) as a dopant. It was demonstrated that PEI is an effective polymer-reducing agent for the n-doping of PDI toward the controllable generation of radical anions.

2020年3月5日 · Perylenediimide (PDI) is one of the most important classes of dyes and is intensively explored in the field of functional organic materials. The functionalization of this electron-deficient aromatic core is well-known to tune …

2023年3月27日 · The emblematic perylenediimide (PDI) motif which was initially used as a simple dye has undergone incredible development in recent decades. The increasing power of synthetic organic chemistry has allowed it to decorate PDIs to achieve highly functional dyes.

2021年12月23日 · In this Perspective, we describe how different modes of contortion can be reliably installed into PDI-based molecules, oligomers, and polymers. We also describe how these different contortions modify the observed optical and electronic properties of PDI.

2022年2月11日 · Perylene diimide (PDI) as a classical dye has some advantages, such as structural diversity, tunable optical and electronic properties, strong light absorption, high electron affinity, and good electron-transporting properties and stability.

Chemical structure of PDI-cored guanidinium-dendrimer 46. A series of PDI-cored dendrimers with three generations were synthesized in high yields (over 90%) by Yin et al. [14] using two kinds of “click” reactions: one is the reaction between primary amines and acrylate groups; the other is the reaction between thiol groups and methacrylates.

Perylene diimides (PDIs) are an important class of organic dyes, which have been explored extensively in their native (charge-neutral) forms. 1 Recently, there has been significant interest in photochemical applications of the one-electron reduced (monoanion) forms of PDIs, whereas the two-fold reduced (dianion) PDI species have attracted less a...
