“…As the relative intensity of the harmonic peaks is the projected electron occupancy along the stacking axis between the layers, such a subtle but visible difference is consistent with the fact that the tethering functional group is not at the same position on the organic backbone. 37 The anchoring to the hydroxyl-bearing inner surface defines the arrangement of the guest molecule as well as other factors. Regardless of the intercalated molecule, the structures of the two LDH prepared are the same with a basal spacing of 1.84 nm corresponding to the distance imposed by the PPA spacer.…”

“…The synthesis of the title compound derives from previous works on the microwave-assisted functionalization of Ta-oxide and Nb-oxide with perovskite structure by amines or alcohols, by us [41][42][43] and others. [39,40] Even though a preintercalation step remains necessary, the use of solvothermal and microwave conditions allows to speed up considerably the reaction times with respect to classical reaction conditions (3 h vs. 48 h).…”

HypothesisWhile controlled and efficient exfoliation of layered oxides often remains a time consuming challenge, the surface modification of inorganic nanosheets is of outmost importance for future applications. The functionalization of the bulk material prior to exfoliation should allow the application of tools developped for Van der Waals materials to directly produce functionalized oxide nanosheets. ExperimentsThe Aurivillius phase Bi 2 SrTa 2 O 9 is functionalized by a linear aliphatic phosphonic acid via microwave-assisted reactions. The structure of the hybrid material and the coordination of the phosphonate group is scrutinized, notably by Pair Distribution Function. This functionalized layered oxide is then exfoliated in one hour in organic solvent, using high shear force dispersion.The obtained nanosheets are characterized in suspension and as deposits to check their chemical integrity. FindingsThe covalent functionalization decreases the electrostatic cohesion between the inorganic layers leading to an efficient exfoliation in short time under shearing. The functionalization of the bulk material is preserved on the nanosheets upon exfoliation and plays a major role to enable liquid-phase exfoliation and in the stability of the resulting suspensions. This strategy is very promising for the straighforward preparation of functionalized nanosheets, paving the way for versatile design of new (multi)functional hybrid nanosheets for various potential applications.

This study presents the intercalation into Layered Double Hydroxides (LDHs) of two sulfonated organic molecules featuring the mesoionic triazolium scaffold. These sulfonated fluorophores exhibited excellent solubility in aqueous basic solutions, facilitating their compatibility with the synthesis of LDHs through coprecipitation methods. We applied the size-matching interlayer space (SMIS) approach by substituting a portion of a mono- or dianionic surfactant used in LDHs preparation by the sulfonated fluorophore, we aimed to match the size of the luminescent interleaved guest effectively. Our investigation focused on two anion spacers: the classic monoanionic dodecyl sulfate (DS) and the dianionic phenylene dipropionate (PPA). Our results indicated that the latter spacer allowed a more efficient insertion of the fluorescent guest. Thermal resistance analysis underscored the robustness of the final hybrid materials, suggesting a promising design strategy for luminescent materials when applied in diverse applications.
