A cavitand-based supramolecular artificial light-harvesting system with sequential energy transfer for photocatalysis

Abstract

A novel artificial light-harvesting system, featuring sequential energy transfer processes, has been successfully constructed and demonstrated white light emission through precise adjustment of the donor-acceptor ratio. To better mimic natural...

Artificial light-harvesting nanoparticles based on a tripodal fluorescence sensor mediated by multiple luminescence mechanisms

“…1,2 The absorbed energy was stepwise transferred in chlorophyll and eventually reaches the reaction center. Inspired by nature, many artificial light-harvesting systems (LHSs) 3–9 have been reported in recent years for different applications, such as photocatalysis, 10–23 bio-imaging, 24–26 information encryption 27–29 and light-emitting devices. 30–33 These systems are often nanoparticles (NPs) dispersed in aqueous media to meet the requirement of green production.…”

Carbazole-based artificial light-harvesting system for photocatalytic cross-coupling dehydrogenation reaction

“…However, with ESY encapsulated in WPP5-CTD , the fluorescent color of the WPP5-CTD-ESY nanoparticle solution gradually changed into yellow, corresponding to the light-harvesting process. Subsequently, based on previous literature, 31–34 the energy transfer efficiency and antenna effect were tested to evaluate the light-harvesting ability of WPP5-CTD-ESY (Fig. 3 and Table S1, ESI†).…”

Multi-step FRET systems based on discrete supramolecular assemblies

“…Recently, Hu and co-workers reported a supramolecular LHS with cascade energy transfer for photocatalysis based on cavitand (Fig. 3c) 96 . Resorcinarene-based cavitands are a class of macrocyclic compounds with deep cavities that have been widely used in supramolecular chemistry.…”
