Summary: A fast, simple, sensitive and stable turn-on fluorescent probe method was developed using the self-assembly of aggregation-induced emission luminogen 1,1,2,2-tetra(biphenyl-4-yl)ethene and cucurbit[7]uril for the selective determination of metformin. The host-guest complex improves the water solubility of traditional aggregation-induced emission material. The method shows good sensitivity and accuracy for metformin detection with a linear correlation between relative fluorescence intensity and metformin concentration in the range of 5 to 100 μM.

Summary: In this study, we report benzofuro[2,3-c]isoquinolines (FiQ) as novel blue AIEgens, in which a -OMe group substituent plays a crucial role in modulating intermolecular interactions, inducing a marked increase in emission of up to 150- and 460-fold in the aggregate and solid states, respectively. Our single-crystal X-ray diffraction analysis revealed that the edge-to-face interactions among phenyl groups generate tight networks that rigidify the assembled structures, resulting in AIE.

Summary: Utilizing nonplanar conjugated molecules for self-assembly is challenging but important. In this study, the self-assembly process of a nonplanar conjugated molecule with aggregation-induced emission (ALE) feature was demonstrated, driven by amphiphiles. The superhigh aggregation-sensitive emission provided precise information about the self-assembly process. The arrangements of ALE-active molecules changed from disordered to well-organized forms by reducing the twisted configuration. The obtained vesicles showed superhigh thermal stability and promising light-harvesting applications.

Summary: This study investigates the relationship between solid-state luminescence and photocyclization of oligoaryl alkene chromophores by modulating the conjugation length. It is found that the emission of heptaaryl cycloheptatriene is turned off upon breaking the conjugation, but extended polycyclic frameworks can be formed. This method can be used to manipulate emission properties and selectively cyclize aromatic compounds.

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: Clusteroluminescence (CL) materials, a class of luminescent materials with unique properties, have gained increasing attention for their theoretical significance and potential in biological applications. However, the emission mechanism remains a challenge, although through-space interaction has been proposed as a preliminary mechanism. This review summarizes the current understanding of CL materials and discusses strategies to achieve high quantum yield and adjustable emission color. The review also provides a perspective on the mechanism and application of CL materials, inspiring researchers in the development of new functional materials.

The photoluminescence of these compounds can be easily tuned by external factors such as excitation wavelength, compression, and oxygen. The clustering-triggered emission (CTE) mechanism can explain these photophysical properties well.

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.
