Embedding CsPbBr₃ quantum dots into a pillar[5]arene-based supramolecular self-assembly for an efficient photocatalytic cross-coupling hydrogen evolution reaction

Abstract

Light-harvesting is a key step in photosynthesis, but it is still a challenge to create an efficient artificial light harvesting system in the broader solar spectrum to mimic natural processes....

Confinement and passivation of perovskite quantum dots in porous natural palygorskite toward an efficient and ultrastable light-harvesting system in water

“…S23 † ) shows that the average lifetime ( τ ) of RB ( λ ex = 541 nm) was 1.0 ns, providing more evidence for the sequential two-step energy transfer. These results suggest that the CsPbBr 3 @PAL composite successfully behaves as a donor in ALHS, and sequential two-step FRET instead of charge transfer 34 is achieved from the CsPbBr 3 QDs to ESY, and then to RB in the relay mode ( Fig. 5e ).…”

“…[28][29][30] These advantages make perovskite QDs an attractive alternative to highly efficient light-harvesting antennas for collecting solar energy in ALHSs. [31][32][33][34] Despite enormous efforts, due to phase transition in water vapor or the aggravation of lattice vibration at high temperature, 35,36 All publication charges for this article have been paid for by the Royal Society of Chemistry and under mild conditions. Therefore, it is a daunting task to realize perovskite-based ALHSs with the sequential FRET regime in aqueous environments, and it has not yet been basically ful-lled.…”

Waste Leather Scrap Hydrolysate: A High-Quality Multidentate Ligand for In Situ Growth of Highly Stable CsSnCl3 Perovskite Nanocrystals

“…This was because the WLSH provided a rich source of nitrogen and carbon for the growth of mildew, thereby accelerating the growth of mildew. In contrast, due to the presence of NCs, [AMIM]­Cl/WLSH-NCs-EC had very little mildew growth, which may be related to the potential photocatalytic , properties of NCs. [AMIM]­Cl/WLSH-NCs had antimold performance, which was obviously beneficial to the WLSH’s long-term protection of NCs.…”

Self-assembled supramolecular artificial light-harvesting nanosystems: construction, modulation, and applications

“…The host-guest complexation between pillararenes and alkyl chains has been also utilized for constructing metal-organic nano-ALHS. 83 As shown in Fig. 1D, CsPbBr 3 quantum dots were synthesized as light-harvesting donors, whose emission band showed a good overlap with a common fluorescent acceptor, ESY.…”
