“…Notably, AIE-based LHSs have drawn much interest recently. [27][28][29][30] The use of AIE donors greatly mitigates uorescence quenching in organic NPs, in which uorophores are packed closely. Moreover, selfabsorption is also detrimental to the uorescence efficiency of organic NPs.…”

“…The amphiphile CSO with CS rigid rod and OEG coils was synthesized by the condensation of compound 1 and compound 2 in dry tetrahydrofuran at room temperature for 12 h (Scheme 1). Precursors 1 [12b] and 2 [11] were synthesized according to our previous reports. CSO was fully characterized by 1 H NMR, 13 C NMR, and high‐resolution ESI‐MS (Scheme S1 and Figure S1–S3 in the Supporting Information).…”

Responsive fluorescent nanomaterials have been received considerable attention in recent years. In this work, a bola‐type amphiphilic molecule, CSO, was synthesized which contains a hydrophobic cyanostilbene core and hydrophilic oligo(ethylene glycol) (OEG) coils at both sides. The cyanostilbene group is aggregation‐induced emission (AIE) active, while the OEG coils are thermo‐responsive. As a result, the CSO molecules can self‐assemble into blue‐fluorescent nanoassemblies with lower critical solution temperature (LCST) behavior in aqueous media. It is noteworthy that the LCST behavior can be reversibly regulated with changes in concentration and the introduction of K+. Intriguingly, fluorescence of CSO assembly shows a blue‐shift upon heating. Finally, by employing CSO as a light capturing antenna and energy donor, an artificial light harvesting system with tunable emission and thermo‐responsive characteristics was fabricated. This study not only demonstrates an integrated approach to create responsive fluorescent nanomaterials, but also shows great potential for producing luminescent materials and mimicking photosynthesis in nature.

“…The shortcomings of the above synthetic methods (difficult synthesis and separation, high environmental requirements) can be solved by effective molecular design and functionalized assembly in artificially simulated light‐harvesting systems. So far, the light‐harvesting systems based on supramolecular assemblies mainly include several categories: macrocyclic compounds, vesicles, [15–18] proteins [19–22] and organic nanomaterials, [23–25] organogel materials, organic‐inorganic hybrids, liquid crystal materials, and so on.…”

Supramolecular self‐assembly is the process of forming aggregates with a certain microscopic arrangement by using intermolecular interactions to join. Due to the dynamic controllability of supramolecular systems, many supramolecular systems with different functions can be precisely constructed through the design and modification of molecules. The world is now facing a crisis caused by energy problems, and the use of solar energy, especially how to achieve efficient collection of light energy like photosynthesis in nature, has become a challenge. Scientists have come up with the idea of using the tunable nature of supramolecular structure and function to construct artificial light harvesting systems, and have developed a series of ALHS based on this. Currently, ALHS have been applied to imaging, sensors, photoelectric conversion and molecular recognition, laying the foundation for the development and efficient use of light energy. This paper will review the mechanism and method of constructing ALHS based on Supramolecular Self‐assembly, the current hot materials for constructing ALHS and their characteristics, as well as the prospects and applications.

An ultralow-acceptor-content supramolecular light-harvesting system for white-light emission

Abstract: White-light emission in donor-acceptor systems usually requires relatively high content or multiple acceptors to “neutralize” the primary-color of the donor. Herein, a cyanostilbene-bridged ditopic ureidopyrimidinone donor (CSU) was designed and...
