Summary: Luminescent liquid crystalline polymers (LLCPs) with potential applications in various fields have been studied. However, LLCPs with conventional luminophores often lose their fluorescence signals in the aggregated state. In this study, we synthesized three main-chain LLCPs with alpha-cyanostilbene (CS) and bifuran units, which showed aggregation-induced emission (AIE) characteristics. The addition of bifuran units improved the toughness of LLCPs and allowed for the formation of flexible films. The polymers underwent reversible isomerization in solution and [2+2] cycloaddition in solid films. The ability to directly print fluorescent patterns on flexible films makes them promising for applications in information storage and anti-counterfeiting.

Summary: In this study, two anthracene-based molecules with the same skeleton but different end groups were designed and synthesized. M-4VB exhibited strong green fluorescence and excellent aggregation-induced emission behavior, while M-MMA showed relatively weak emission. The enhanced emission behavior of M-4VB in both solid state and aggregation state was attributed to the more rigid environment and stronger intermolecular hydrogen bonding interactions.

Summary: The incorporation of mechanochromic luminescence into TADF molecules is a promising strategy for developing multifunctional mechanochromic luminescent materials. In this work, the delayed fluorescence lifetime of 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene crystals was found to be continuously shortened with increasing pressure. The study developed a new function of TADF molecules and provided a route to shorten the delayed fluorescence lifetime, which is beneficial for designing TADF-OLEDs with small efficiency roll-off.

Summary: This study presents a polymerization-induced phosphorescent emission (PIPE) method, which transforms non-luminescent monomers into luminescent polymers through non-conjugated bond formation. The luminescent properties can be tuned by using different monomer compositions. The resulting polymer with PIPE activity exhibits high photo efficiency, potentially due to interactions among repeating units. Combining with blue-emitting carbazole monomer generates white-light-emitting copolymers.

Summary: This study utilizes solid-state intramolecular motion of AIE molecular rotors and fibers to develop highly sensitive optical fiber sensors responsive to ambient humidity with observable chromatic fluorescence change. The sensors provide a linear response to humidity by inducing intramolecular motions of AIE molecules through swelling of polymer fibers in moisture environments. This approach offers a process-friendly architecture and physically tunable medium for manipulating fluorescence response characteristics, allowing for hierarchical sensor structures adaptable for spatial-temporal humidity mapping and device integration for light-emitting sensors and touchless positioning interfaces.

Summary: The construction of high quantum yield solid-state fluorescent materials is crucial for preparing organic light-emitting devices. In this study, a solid-state mechanochemical grinding method was used to prepare an AIEgen-based emissive hydrazone-linked covalent organic polymer (TFBE-TD COP). The COP exhibits good emission and high fluorescence quantum yield in the solid-state due to its rigid structure and aggregation induction. The material also shows rapid response and high sensitivity to trifluoroacetic aid gas, as well as the ability to achieve white-light emission when coated onto a blue LED.

Summary: Solar water purification technology is an effective and affordable method for obtaining fresh water. However, the efficiency of purification is limited by high ion concentration, organic pollution, and biological pollution. In this study, a porous hydrogel membrane (Fe/TA-TPAM) was developed for the purification of contaminated water. The membrane has good light absorption and photothermal conversion abilities, resulting in high evaporation rates and solar efficiency. With the addition of tannic acid (TA) and Ti3C2 MXenes, the Fe/TA-TPAM membrane exhibits satisfactory purification properties for organic-contaminated and biologically contaminated water. These findings provide a novel strategy for designing advanced photothermal conversion membranes for water purification.

Summary: This study developed phase-change thermoregulated nanofiber membranes using polyethylene glycol (PCM) as the phase change material and polyacrylonitrile (PAN) as the polymer backbone, with increased thermal conductivity by adding spherical nano-alumina (Al2O3) through coaxial electrospinning technology. The membranes exhibited excellent thermal responsiveness and thermoregulation when 5% Al2O3 was added. They had a high melting enthalpy of 60.05 J·g(-1) and retained a high enthalpy after 50 cycles of cold and heat, withstanding sudden changes in ambient temperature well. Additionally, the nanofiber membranes had good air and moisture permeability, enhancing wearer comfort. Therefore, they can be considered as a promising textile for personal thermal management.

Summary: In this study, the effects of three different dopants (Mg, Sr, and Ba) on the structure of C-S-H-tobermorite were investigated using DFT calculations. The results showed that Mg doping led to a decrease in lattice volume and significant changes in the structure and coordination of magnesium-oxygen polyhedra. On the other hand, Sr and Ba doping only increased the volume of the respective oxygen polyhedra. Despite distorting the structure, Mg doping improved the compressive and shear resistance of tobermorillonite, while having less effect on the anisotropy of the Young's modulus. The findings suggest that Mg doping is a promising approach for optimizing the structural design of C-S-H.
