Construction of FRET-based metallacycles with efficient photosensitization efficiency and photocatalytic activity

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][4][5][6][7][8][9] have been reported in recent years for different applications, such as photocatalysis, [10][11][12][13][14][15][16][17][18][19][20][21][22][23] bioimaging, [24][25][26] information encryption [27][28][29] and light-emitting devices. [30][31][32][33] These systems are often nanoparticles (NPs) dispersed in aqueous media to meet the requirement of green production.…”

Assembling aggregation‐induced emission with natural DNA to maximize donor/acceptor ratio for efficient light‐harvesting antennae

“…[26] In principle, the effective distance of Förster resonance energy transfer (FRET) is ∼10 nm, and thus 30 base pairs (∼60 phosphate groups) could be extended in the opposite directions along the DNA backbone with a minor groove as the center. [28,29] If the donor chromophores are ideally attached to each phosphate group by electrostatic interaction, and the energy acceptor only binds to the minor groove through hydrophobic interaction, efficient light-harvesting antennas could be self-assembled with a donor/acceptor ratio of 120:1. However, such a close packing of donor chromophores would induce intractable aggregation-caused quenching (ACQ) problem.…”

Construction of an efficient artificial light-harvesting system based on hyperbranched polyethyleneimine and improvement of photocatalytic performance

“…As a kind of efficient photocatalyst, ALHSs can fully improve the absorption and utilization efficiency of light, and then more effectively simulate natural photosynthesis. Photocatalytic systems incorporating ALHSs have been effectively utilized in a range of photocatalytic organic reactions, such as dehalogenation reactions, cross dehydrogenative coupling (CDC) reactions, oxidation reactions, hydrogen evolution reactions, alkylation reactions, and other reactions, [28][29][30][31][32][33][34][35][36][37][38][39][40] as evidenced by extensive research efforts. However, almost all of the reported photocatalytic reactions exhibit limited competitiveness compared with natural photosynthesis, as well as other catalytic approaches.…”
