Summary: In this study, multi-emission carbon dots (M-CDs) with three emissions were synthesized and their luminescence mechanism was investigated in detail. The high-concentration M-CDs showed emissions at 423 nm and 586 nm, while the emission at 493 nm was mainly due to self-absorption. On the other hand, low-concentration M-CDs only had emissions at 423 nm and 586 nm. Solid CDs (S-CDs) with solid-state room temperature phosphorescence (RTP) were also obtained, and their mechanism was found to be related to the presence of NaHCO3 acting as an oxygen barrier. The M-CDs were successfully used for detecting Morin, while the S-CDs were applied for optical anti-counterfeiting purposes.

Summary: This study designed and prepared three molecular weight polymers and investigated the changes in their fluorescence emissions. By doping these polymers into a PAN matrix, molecular weight-dependent polymeric RTP materials were successfully achieved, and a redshift phenomenon was discovered, which may be attributed to different aggregation states formed by assembly of different molecular weight polymeric chains. These polymeric phosphors can be used as anti-counterfeiting ink for advanced information encryption.

Summary: This article presents the achievement of cluster-induced aggregation, multicolour luminescence, and ultra-long phosphorescence in non-conjugated luminescent polymers (NCLPs) based on linear polyurethane derivatives. By adjusting the reaction temperature and time, the authors successfully prepared NCLPs with ultra-long room temperature phosphorescence lifetime of 0.45 s. DFT calculations and molecular dynamics simulations provided detailed microstructural information on the polyurethane derivatives, revealing the underlying luminous mechanism. The potential of the polyurethane derivatives in information security was validated through experimental encryption/decryption models. These findings have important implications for understanding unconventional luminescence mechanisms and strategic design of NCLPs for practical applications.

Summary: Chlorophyll (Chl) has great potential as a colorant and functional ingredient in food development, but its weak stability limits its application. This study demonstrates that ternary synergistic aggregation of Chl/SPI can enhance Chl stability. Under heat treatment, the Chl/Pr synergistic aggregation significantly improves Chl retention compared to low and high-concentration Chl samples. Spectral analysis and microscopic observation confirm the existence of Chl/Pr synergistic aggregation. The self-aggregate of Pr creates an ideal hydrophobic cavity for Chl self-aggregation, enhancing its stability. The study provides insights into the Chl/Pr interaction mechanism and offers new ideas for improving natural pigment stability.

Summary: In this study, we investigated the influence of donor and acceptor groups substituted on a twisted three-fold symmetric hydrocarbon homotruxene. The results show that the twisted pi-system of the homotruxene allows it to exhibit persistent room temperature phosphorescence (RTP) even without any donor or acceptor moieties. In solution, a donor methoxy group increases the phosphorescence decay rate, while in the solid-state, molecular aggregation and packing result in a very persistent phosphorescence visible to the naked eye. Additionally, polar substituents modulate the RTP of the inherently nonpolar homotruxene mainly through altered crystal packing.

Summary: Research on amorphous pure organic room-temperature phosphorescent materials with dual-emissive properties has led to the development of color-tunable RTP emission, including white-light emission, under different feeding ratios and excitation wavelengths. Additionally, time-dependent multicolor afterglow, including nearly white afterglow, can be observed. The RTP emission of the water-soluble acrylamide copolymers can be quenched by water, resulting in tunable emission colors under different humidity conditions.

Summary: This study focuses on the stimuli-responsive luminescence of a novel emitter, DCzPy, which emits bluegreen fluorescence in crystal form. Upon gentle grinding, the fluorescence intensity of DCzPy is significantly enhanced with a hypsochromic shift. The emission wavelength returns to its original value after heavy grinding. Moreover, DCzPy exhibits a large bathochromic-shifted and weakened fluorescence under isotropic compression. In film form, the thermoresponsive behavior of DCzPy changes the emission from green to blue. Based on this thermo-induced fluorescence switching, a two-dimensional code for information anticounterfeiting is successfully fabricated.
