“…In the presence of two other types of surfactants (anionic and non‐ionic), no decrease in pH was observed (Table S6, Supporting Information), which may be attributed to the effects of different micellar properties, charge, and nuclear size. [ 24 ] In the whole system, the highly deprotonated H 3 BTC ligand makes it easier for Bi 3+ to form a more stable nine‐coordinate structure. The significance of the ultrasound was proven through the control experiments, and no CAU‐17‐CTAB was discovered at all ultrasound‐free conditions described detailed in Supporting Information (Figure S23, Supporting Information).…”

Green synthesis of stable metal‐organic frameworks (MOFs) with permanent and highly ordered porosity at room temperature without needing toxic and harmful solvents and long‐term high‐temperature reactions is crucial for sustainable production. Herein, a rapid and environmentally friendly synthesis strategy is reported to synthesize the complex topological bismuth‐based‐MOFs (Bi‐MOFs), [Bi9(C9H3O6)9(H2O)9] (denoted CAU‐17), in water under ambient conditions by surfactant‐mediated sonochemical approach, which could also be applicable to other MOFs. This strategy explores using cetyltrimethylammonium bromide (CTAB) amphiphilic molecules as structure‐inducing agents to control the removal of non‐coordinated water (dehydration) and enhance the degree of deprotonation of the ligands, thereby regulating the coordination and crystallization in aqueous solutions. In addition, another two new strategies for synthesizing CAU‐17 by crystal reconstruction and one‐step synthesis in binary solvents are provided, and the solvent‐induced synthesis mechanism of CAU‐17 is studied. The as‐prepared CAU‐17 presents a competitive iodine capture capability and effective delivery of the antiarrhythmic drug procainamide (PA) for enteropatia due to the broad pH tolerance and the unique phosphate‐responsive destruction in the intestine. The findings will provide valuable ideas for the follow‐up study of surfactant‐assisted aqueous synthesis of MOFs and their potential applications.

Carbamazepine (CBZ) was incorporated into layered double hydroxides (LDH) to be used as a controlled drug system in solid tumors. CBZ has a formal charge of zero, so its incorporation in the anionic clay implies a challenge. Aiming to overcome this problem, CBZ was loaded into LDH with sodium cholate (SC), a surfactant with negative charge and, for comparison, without SC by the reconstruction method. Surprisingly, it was found that both resultant nanocomposites had similar CBZ encapsulation efficiency, around 75%, and the LDH-CBZ system without SC showed a better performance in relation to the release kinetics of CBZ in simulated body fluid (pH 7.4) and acetate buffer simulating the cellular cytoplasm (pH 4.8) than the system with SC. The CBZ dimensions were measured with Chem3D and, according to the basal spacing obtained from X-ray patterns, it can be arranged in the LDH-CBZ system as a monolayer with the long axis parallel to the LDH layers. Fourier transform infrared spectroscopy and solid state NMR measurements confirmed the presence of the drug, and thermogravimetric analyses showed an enhanced thermal stability for CBZ. These results have interesting implications since they increase the spectrum of LDH application as a controlled drug system to a large number of nonionic drugs, without the addition of other components.
