1-methyl-2-pyrrolidone( 1m2p)i sasolvent with proven abilitiesf or 2D-solid exfoliation due to its extremely high surface tension. In principle, such af eature could be used also to induce the selectiveb reaking of certain bonds in solids to obtain new materials. Such ah ypothesis is demonstrated in this study for transition metal nitroprussides, where 2D solids are obtained from 3D frameworks by selective rupture of axial bonds. This contribution discusses the mechanism involved in such molecular manufacture. The crystal structuref or the formed 2D solids was solved and refined from XRD powder patterns recordedu sing synchrotron radiation.M çssbauer,I Ra nd Ramans pectrap rovided fine details on the electronic structure of the resulting new series of layered materials. The experimental information was complemented with calculations for the molecule configuration in its non-activated and activated forms. In the obtained 2D solids,n eighboring layers of about 1nmo ft hickness remain separated by activated1 m2p molecules. The interaction betweenn eighboring layers is of ap hysicaln ature, withoutt he presence of ac hemical bond between them,a sc orresponds to a2Dm aterial.For 1m2p: n(C =O) = 1688 cm À1 and n(NÀC CH3 ) = 1402 cm À1 ;[ a] Ta ken from Raman spectrum.

“…The decrease in the magnetic response of the metallopolymer as compared to the pristine material was attributed to the loss of the overlap among the π clouds brought about by the bulky complexed site. This argument was also used to account for the magnetic results reported in a recent publication for similar systems, indicating that π stacking is a favorable factor for the enhancement of the magnetic properties. Morphological effects on the packing of conjugated polymer chains have been addressed in a number of publications …”

“…This situation is the most favorable to π–π stacking, and according to published data, a good interaction between the applied magnetic field and the polymer backbone is obtained when the chains are aggregated. Therefore, the origin of the ferromagnetic behavior in low temperatures of the pure LaPPS75 could be accounted to π–π stacking formation, where the trans–trans configuration is closest to the coplanar.…”

Poly[9,9′‐dihexylfluorene‐2,7‐diyl)‐6,6″‐(2,2′:6′,2″‐terpyridine)] (LaPPS75) and its complexes with neodymium were synthesized and characterized. Magnetic measurements showed that the noncomplexed polymer presented a ferromagnetic contribution due to the formation of π stacking, and that in absence of those, the ferromagnetic behavior is suppressed. The pristine polymer, the complexed one and a low‐molecular‐weight model compound with the same structure of the complexed site in the parent polymer were studied. The observed behavior found is presented and discussed, the most important finding was that when a conjugated chain is used as a host for the metallic ion, an amplification of four times for the magnetization is achieved, using the same metallic content for complexed polymer and model compound for comparison. © 2019 Wiley Periodicals, Inc.

This study explores various aspects of Metal‐Organic Frameworks (MOFs), focusing on synthesis techniques to adjust pore size and key ligands and metals for crafting carrier MOFs. It investigates MOF‐drug interactions, including hydrogen bonding, van der Waals, and electrostatic interactions, along with kinetic studies. The multifaceted applications of MOFs in drug delivery systems are elucidated. The morphology and structure of MOFs are intricately linked to synthesis methodology, impacting attributes like crystallinity, porosity, and surface area. Hydrothermal synthesis yields MOFs with high crystallinity, suitable for catalytic applications, while solvothermal synthesis generates MOFs with increased porosity, ideal for gas and liquid adsorption. Understanding MOF‐drug interactions is crucial for optimizing drug delivery, affecting charge capacity, stability, and therapeutic efficacy. Kinetic studies determine drug release rates and uniformity, vital for controlled drug delivery. Overall, comprehending drug‐MOF interactions and kinetics is essential for developing effective and controllable drug delivery systems.
