Fluorescence resonance energy transfer (FRET) from the excited state of donor to ground acceptor is one most important fluorescence mechanisms and has wide applications in light-harvesting systems, light-mediated therapy, bioimaging, optoelectronic devices, information security fields. The phenomenon sequential natural photosynthetic systems provides great inspiration for scientists make full use light energy. In recent years, discrete supramolecular assemblies (DSAs) have been successively constructed incorporate multiple acceptors, achieve multi-step FRET between them. This perspective describes advances fabrication application DSAs with FRET. These are categorized based on non-covalent scaffolds, such as amphiphilic nanoparticles, host-guest assemblies, metal-coordination biomolecular scaffolds. will also outline opportunities future challenges this research area.

Constructing highly efficient artificial light-harvesting (LH) systems via a scaffold-free approach for capturing and utilizing light energy to emulate photosynthesis-inspired transfer processes is great challenge. Herein, we report an nanoparticle (LHN) based on two derivatives of tetraphenylethylene as donor/acceptor (D/A) pair in skeleton compact effective stacking prepared by simple ultrasound-assisted self-assembly within ∼1 h water aggregation-induced emission (AIE) effect intermolecular transfer. By simply adjusting the D/A mixture ratio, LHN shows tunable multicolor (from cyan near-infrared) with remarkable efficiency 96.5% at ratio 50:1 attains high antenna 79.2 4000:1. Importantly, exhibits nearly pure white color coordinates (0.32, 0.35) 300:1 quantum yield 51%. Moreover, our biocompatibility brightness cellular imaging MCF-7 cells over 3 days. Compared direct excitation acceptors uptaken LHN, it approximately 14-fold enhancement cell brightness. This fabrication strategy opens up possibilities large-scale AIEgen-based luminescent materials potential applications fields real-time imaging.
