Supramolecular polymer-directed light-harvesting system based on a stepwise energy transfer cascade

Abstract

The design and construction of artificial light-harvesting system in water by mimicking the energy transfer cascade in natural photosynthesis are of significant importance. Herein, we report an efficient two-step sequential...

A novel polyelectrolyte-based artificial light-harvesting system for photocatalysis of cross-dehydrogenation coupling

“…Inspired by the process of photosynthesis, researchers have constructed various types of articial light-harvesting systems (LHSs) that transfer energy based on the Förster resonance energy transfer process (FRET). Aer years of painstaking research, various articial LHSs based on supramolecular polymers, [1][2][3][4][5] host-guest interactions, [6][7][8][9][10][11][12][13][14][15][16][17] gels, [18][19][20][21] vesicles, and micelles [22][23][24][25][26] have been reported. However, these articial light-harvesting systems are constructed using methods that have to go through many complex steps.…”

Interface Engineering of Bi‐Fluorescence Molecules for High‐Performance Data Encryption and Ultralow UV‐Light Detection

“…Therefore, OA is one of the excellent and efficient candidates for regulating excited-state luminescence. [41][42][43][44] Here, we successfully regulated the luminescence of a series of difluoroboron β-diketonate (DFBK) chromophores that were emitted from different electronically excited states at the interface of oleic acid molecules. Selective excitation of OA in the OA-DFBK composites led to blue luminescence, which could be attributed to the locally excited state emission of the DFBK (Figure 1a).…”

An artificial light-harvesting system with sequential energy transfer for information dual encryption and anticounterfeiting

“…In recent years, a variety of artificial light-harvesting systems (LHSs) have been developed to mimic natural LHSs, including conjugated polymers, 14 supramolecular self-assembly, [15][16][17][18][19][20][21][22][23] supramolecular phosphors, 24,25 micelles, 26,27 dendrimers, 28 coordination compounds, [29][30][31][32] conjugated polymeric supramolecular network, 33 nanocrystals, 34 etc. Since LHSs can capture and transfer sunlight, a green and renewable energy source, into a variety of energies such as light, electric, chemical and so on, the LHSs have shown extensive applications in photochemical catalysis, [35][36][37][38][39] biosensing and imaging, [40][41][42][43][44][45] photothermal therapy, 46 third-level fingerprint imaging, 47 etc.…”
