“…The band at 1381 cm −1 (NO 3 − ) in the Fourier‐transform infrared (FTIR) spectrum (Figure S2, Supporting Information) disappeared simultaneously with the appearance of the characteristic absorption peaks of BP4 and DES anions, which suggests that the NO 3 − anions were completely replaced by BP4 anions. [ 22–25 ] Notably, the high hydroxyl‐group absorption peaks (3480 cm −1 ) of DES–BP4 ( x %)/LDH were slightly shifted to smaller wavenumbers than that of NO 3 ‐LDH (3561 cm −1 ), which suggests hydrogen bondings between the rigid LDH layers, DES, and BP4 anions. [ 26 ] These results confirm that DES and BP4 were successfully cointercalated into the LDH interlayers, as shown in Scheme 1.…”

Considering the anionic intercalation capacities of layered double hydroxides (LDH), 2‐hydroxy‐4‐methoxybenzophenone‐5‐sulfonate (BP4) and decanesulfonate (DES) anions are cointercalated into the interlayers of Mg2Al‐LDH to form DES–BP4 (x%)/LDH composites, which can be regarded as 2D interlayer supramolecular infinite solid solutions (2D ISISSs), according to a structural analysis. Compared to those of pristine BP4, the fluorescence properties of DES–BP4 (x%)/LDH 2D ISISSs are significantly improved and their emission peak wavelengths are adjustable in the range of 491–510 nm by varying x. DES–BP4 (8%)/LDH exhibits the optimal fluorescence properties. Its quantum yield, lifetime, and fluorescence intensity are increased ≈14, 4, and 45 times, respectively. Moreover, its nonradiative relaxation rate constant is decreased five times, while its radiative relaxation rate constant is increased three times. The luminescence enhancement can be attributed to the formation of the 2D ISISSs system, which effectively restricted the intramolecular movements of BP4 anions. Owing to its enhanced fluorescence properties, DES–BP4 (8%)/LDH exhibits outstanding performances for cell penetration and confocal fluorescence imaging and lifetime imaging of lysosome in HeLa cells. Therefore, the 2D ISISSs based on the LDH matrix provide a novel route to optimize the performances of functional molecules and expand their applications.

“…Previous studies have reported that LDH can inhibit the photo‐oxidation of asphalt and WPCs during weathering . In addition, owning to the ready exchangeability of their interlayer anions, several UV absorbers have been intercalated into LDH with a supramolecular layered structure . After intercalation, both the thermal stability and photostablity of these guest anions within the interlayer space of LDH have been markedly improved …”

In this study, 5‐sulfosalicylic acid (SA) anions have been intercalated into Mg3Al‐NO3 layered double hydroxide (LDH) to synthesize SA‐intercalated Mg3Al‐NO3‐LDH (LDH‐SA) by ion‐exchange reaction. Then, the effects of LDH, SA, and LDH‐SA on the photostability of wood flour/polypropylene (WF/PP) composites during accelerated ultraviolet (UV) weathering were investigated. The surface color, surface gloss, and mechanical properties of the composites during weathering were tested, accompanied by characterizations using SEM, ATR‐FTIR, and TG. The results showed that (1) SA anions completely replaced the NO3− anions in LDH and the thermal stability of LDH‐SA was considerably enhanced; (2) composites with LDH or LDH‐SA exhibited less color change, fewer surface cracks, better thermal stability, and less losses of mechanical properties than the control group; (3) LDH‐SA showed a long‐term efficiency and alleviated the photo‐oxidation of WF/PP composites successfully; (4) LDH‐SA blocked UV light by physical shield effect of the layer sheets, as well as the chemical absorbability of the interlayer anions. © 2016 Wiley Periodicals, Inc.

A novel UV absorption material of squaric acid (SA) anion (C4O 2− 4 ) intercalated layered double hydroxides (LDHs) was successfully synthesized by the co-precipitation method. After intercalation, the interlayer distance of MgAl-SA-LDHs increased to 1.04 nm compared to those of MgAl-CO3-LDHs and SA anions present in form of a monolayer in the interlayer of LDHs. Thermal stability of SA clearly enhanced by the intercalation and the suppression of the deintercalation ability of MgAl-SA-LDHs was superior to that of 4-hydroxy-3-methoxybenzoic acid intercalated LDHs. The results of UV-DRS indicate the potential application of MgAl-SA-LDHs as UV absorbers.
