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

Abstract

Artificial light-harvesting systems, an elegant way to capture, transfer and utilize solar energy, have attracted great attention in the recent years. As the primary step of natural photosynthesis, the principle...

An Inbuilt Electronic Pawl Gates Orbital Information Processing and Controls the Rotation of a Double Ratchet Rotary Motor

“…Thus, we see that the N atom of the −NH 2 group and the O atom of the −OCH 3 group actively contribute to the asymmetric change in dynamic orbital behavior. At ambient temperatures, analysis of 1 H and 13 C NMR spectra of the DRM showed that corresponding proton and carbon peaks attributed an exact number of atoms to the chemical structure of the DRM. No additional peak was observed because of the different rotamer structures.…”

“…Nanotechnology’s ambitious future objective is to make molecular nanofactories; molecular motors − are key to making that happen. By definition, a molecular machine should do some physical work, following information written in its orbitals; whether this orbital information regulates classical thermodynamics has triggered a debate about the thermodynamics of information content. − However, it can potentially transform the fields of energy harvesting, − nanoarchitectonics, − bloodless surgery, , and ultrafast quantum engines …”

A temperature-responsive artificial light-harvesting system in water with tunable white-light emission

“…The construction of articial light-harvesting systems (LHSs) in pure water via supramolecular approaches has been extensively explored in the past decade. [7][8][9] However, such supramolecular LHSs exhibiting temperature-responsive behaviors that mimic natural photosynthesis are less studied. In view of the fact that the assembly of M not only has a temperature response, but also has good luminescent properties, we wondered whether it can be used to construct a temperature-responsive LHS.…”

“…[1][2][3][4] The LHSs found in nature are sophisticated supramolecular assemblies of chlorophyll pigments that were encapsulated together in a protein scaffold. 5 To mimic natural photosynthesis, articial LHSs have been developed in recent years based on assorted supramolecular scaffolds, [6][7][8][9] including biomacromolecules, [10][11][12][13] macrocycles/cages/stacks, [14][15][16][17][18][19][20] nanoparticles, [21][22][23][24][25][26][27] and hybrid materials. [28][29][30][31][32] It is well known that temperature has a great inuence on photosynthesis.…”

A pillar[5]arene-based artificial light-harvesting system with red emission for high-resolution imaging of latent fingerprints

“…[19][20][21][22] Recently, supramolecular light-harvesting systems (LHSs) based on Förster resonance energy transfer (FRET) have attracted significant interest due to their great potential in photocatalysis, bio-imaging and tunable photoluminescent devices. [23][24][25][26][27] An artificial LHS with high energy harvesting efficiency should have a high donor/ acceptor (D/A) ratio, enabling the co-assembly of a tiny amount of ACQ dye as an energy acceptor into a large number of AIE donors to achieve long-wavelength and even red emission.…”
