“…15 The high thermal and photostability of PDI makes it an ideal candidate for water oxidation photocatalyst. Recently, the supramolecular architectures of PDI were employed as antennae chromophores working with the photocatalysts to construct water splitting system, [16][17][18][19] such as PDI-Ni, [16] PDI-Ru, [17] PDI-TiO2 [18] and PDI-C3N4 [19].…”

The development of organic materials for visible light driven photocatalytic is regarded as one of the most promising avenues to solve environment and solar-energy utilization issue. Here, we present that one-dimensional supramolecular organic nanofibers, self-assembled by a carboxy-substituent perylene diimide (PDI) molecule through H-type π-π stacking and hydrogen bonding, can act as a robust and effective photocatalyst for both organic pollutants degradation and water oxidation under visible light without the apparent need for an added metal co-catalysts. We corroborate that the highly efficient and stable activity of such supramolecar photocatalyst are attributed to the introduction of terminal carboxyl group, which leads to well-defined and stable Htype π-π stacking, and constructs the internal electric field in supramolecular nanofibers, thereby resulting in the deepening of valence band (VB) and the enhancement of migration and separation efficiency of photo-induced charge carriers. Our findings may help the development of semiconducting-based organic supramolecular materials for applications in environment protection and water splitting.

“…2,[4][5][6][7] Interestingly, some PBIs are used as LMWGs as they can selfassemble into a wide range of structures as a result of noncovalent interactions including hydrogen bonding, van der Waals interactions and p-p stacking. 8,9 PBIs have also been successfully used as photocatalysts for a range of reactions including hydrogen evolution, [10][11][12][13][14][15][16] water oxidation 17 and the reduction of aryl halides. 18,19 Proton reduction, or the Hydrogen Evolution Reaction (HER), is a widely studied half reaction from the water-splitting process.…”

“…Perylene diimide (PDI) self‐assembly has attracted much attention in solar cells, sensors, fluorescence probes, n‐transistors, and photocatalysts . In photocatalysis, PDI self‐assembly and its composites can be used for photocatalytic hydrogen production, oxygen production, dye degradation, dehalogenation, and CC coupling reaction, attributed to excellent visible‐light absorption, charge conductivity, structural modifiability, morphology controllability, and performance optimization. However, PDI self‐assembly has not been industrialized on a large scale, since there are two main problems: high electron–hole recombination leads to low utilization of the solar energy; and it can only absorb visible light while near‐infrared light and ultraviolet light cannot be effectively utilized.…”

“…To this end, many complexes based on PDI self‐assembly have been prepared, such as C 3 N 4 –PDI, TiO 2 –PDI, and Zn x Cd y S–PDI . Due to interfacial charge transfer, these complexes can greatly boost visible‐light photocatalytic activity due to interfacial charge transfer, but they cannot enhance ultraviolet‐light photocatalytic activity and the research on these aspects was not in‐depth as well.…”

A semi‐core–shell structure of perylene diimide (PDI) self‐assembly coated with TiO2 nanoparticles is constructed, in which nanoscale porous TiO2 shell is formed and PDI self‐assembly presented 1D structure. A full‐spectrum photocatalyst is obtained using this structure to resolve a conundrum—TiO2 does not exhibit visible‐light photocatalytic activity while PDI does not exhibit ultraviolet photocatalytic activity. Furthermore, the synergistic interaction between TiO2 and PDI enables the catalyst to improve its ultraviolet, visible‐light, and full‐spectrum performance. The interaction between TiO2 and PDI leads to formation of some new stacking states along the Π–Π stacking direction and, as a consequence, electron transfer from PDI to TiO2 suppresses the recombination of e−/h+ and thus improves photocatalytic performance. But the stronger interaction in the interface between TiO2 and PDI is not in favor of photocatalytic performance, which leads to rapid charge recombination due to more disordered stacking states. The study provides a theoretical direction for the study of core–shell structures with soft materials as a core, and an idea for efficient utilization of solar energy.
