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...

It is of great significance to combine different fluorescence mechanisms to accurately regulate the properties of organic fluorescent materials, such as Stokes shift, emission intensity and photoluminescence color. In this...

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...

The development of stimuli‐responsive fluorescent materials in water based on organic molecule has drawn significant interest. Herein, we designed and synthesized an amphiphilic molecule M containing a fixed tetraphenylethylene moiety (FTPE) as hydrophobic part and tri(ethylene glycol) (TEG) chains as hydrophilic part. Notably, the FTPE moiety is aggregation‐induced emission (AIE) active, while the TEG chains are thermo‐responsive. M can self‐assemble into fluorescent nanoparticles (NPs) in water, which showed lower critical solution temperature (LCST) behavior. Moreover, its clouding point can be reversibly tuned upon the concentration variation. Interestingly, the NPs can be acted as a fluorescence thermometer in aqueous media owing to their unique AIE and LCST behaviors. Our work herein not only provides an integration strategy to construct stimuli‐responsive fluorescent materials but also shows great potential in biological applications including bioimaging and biosensors.
