Summary: In recent years, aggregation-induced emission luminogens (AIEgens) have been widely used in various fields such as bioimaging, theranostics, organic photoelectronics, and chemo/biosensors. However, the current AIEgens are mostly synthesized organically, which involves complex synthesis routes, high cost, environmental unfriendliness, and poor biocompatibility. Therefore, the exploration of AIEgens from natural products has become an attractive alternative approach. This contribution discovers two natural AIE-active materials, Tangeretin and Nobiletin, which can be extracted from orange peel.

Summary: This study developed a new doped polymer film based on sodium alginate and aromatic carboxylates, which can be easily fabricated through the aqueous solution process. The film is flexible, transparent, and re-dissolvable, and it can exhibit multi-tunable afterglow colors from blue to red and even white. Better controllability can be achieved through co-doping and triplet-to-singlet Forster resonance energy transfer (TS-FRET). The film demonstrates advanced anti-counterfeiting capabilities based on its excitation- and time-dependent as well as TS-FRET-mediated afterglow colors.

Summary: In this study, the co-crystallization between melamine and cyclic imide-based non-conventional luminophores is reported. The resulting co-crystals have multiple hydrogen bonds and effective clustering of electron-rich units, leading to diverse emissive species with rigid conformations and promoted spin-orbit coupling. As a result, p-RTP co-crystals with enhanced efficiencies and lifetimes of up to 12.0% and 898 ms, respectively, are obtained, along with improved color tunability. These findings may contribute to the rational design of high-performance p-RTP materials and advance our understanding of the mechanism behind color-tunable phosphorescence.
