Recent theoretical studies predicted that the frustrated Lewis pair (FLP) formed by carbonaceous species confined in zeolites/zeotypes can activate H-H and C-H bonds. However, there still lacks experimental evidence understanding on role of FLP hydrogenation reaction. Herein, we combined experiments density functional theory (DFT) calculations to demonstrate Brønsted acid sites with weak strength transfer H+ form Si-O--Al as a base carbocation acid. They are electrostatically attracted sterically repelled, thus, forming sites. We present for first time general principle about formation inside zeotypes investigated effect topology formation. active ethylene hydrogenation, their activity is inversely correlated parent strength. derived from weaker promotes C2H4 adsorption H2 activation, thus enhancing hydrogenation. This work not only provides mechanistic insights into origin olefin over metal-free but also offers guidance further development high-performance zeolite/zeotype-based catalysts heterogeneous catalysts.

Noncovalent interactions form the basis of matter and life yet are difficult to characterize. Here we devised a platform strategy systematically build noncovalent with selective chemical groups into precisely designed configurations by using metal-organic frameworks (MOF) as molecular scaffold. Using vibrational Stark effect benchmarked against computer models, found electric field provides unifying metric for quantifying diverse in MOFs solutions. By synthetically making spectroscopically testing collection nitrile probe, identified stabilizing fields strong -123 MV/cm produced additively multiple hydrogen bonds, an unusual destabilizing +6 between antiparallel dipoles , anomalous hydrogen-bond blueshifts large 34 cm-1, unique solvation under nanoconfinement. This method opens new avenues exploring universe interactions.

Abstract Organic fluorophores with through‐space donor/acceptor interaction have garnered significant attention for their unique charge transfer properties and advanced applications. However, use in luminescent applications is hindered by challenges such as low luminescence efficiency, broad emission spectra. Herein, a series of highly emissive thermally activated delayed combining boron‐based multi‐resonance acceptor an arylamine donor within spatially compacted structure designed synthesized. By strategically varying spatial compactness, interactions are fine‐tuned, enabling precise control over high‐lying excited states characteristics while preserving narrow‐spectrum fluorescence. Key structural optimizations, including planar space‐compacting methyl group, resulted compact configuration, boosting reverse intersystem crossing rates 20‐fold compared to the parent fluorophore. This design minimizes concentration‐induced quenching spectral broadening, yielding superior solid‐state luminescence. The resulting organic light‐emitting diodes achieved ultranarrow electroluminescence (full width at half‐maximum 22 nm) remarkable external quantum efficiency 31.1%, along reduced roll‐offs.

ConspectusThe past decades have witnessed the proliferation of porous materials offering high surface areas and revolution in gas storage separation, where metal–organic frameworks (MOFs) stand out as an important family. Alongside pursuit higher area, increase size guests, such nanoparticles biomolecules, has also led to demand for larger space defined by pores cages within MOF structure, from conventional micropore regime (<2 nm) toward mesopore (2–50 nm). Among essential elements design MOFs, molecular building blocks, their coordination spatial arrangement, chemistry design, bonds become relatively mature, precise control shape environment molecularly 3D cages; however, correlation between geometrical parameters polyhedrons describing cages, concerning arrangement is much less explored.In this Account, we made efforts associate actual cage with critical components, vertices, edges, connectivity, rings, underlying polyhedrons, well combination components various types MOFs. Several trends were found, influence connectivity expansion efficiency, insights into construction This enables creation extremely large mesoporous MOFs internal diameter up 11.4 nm small blocks. Furthermore, discuss a strategy partial removal or replacement organic linkers construct readily known topologies.All above urged us ask following questions: Is there any limit sculpting molecules? How area can one chemical bond support? The answer these questions will deepen knowledge efficient utilization spaces guide mesopores. general principals emerged: (1) Expansion efficiency radius are positively correlated number vertices. (2) Increase vertices decrease favor cages. (3) boundary constructed related polyhedron type determined energy involved crystallinity. Such likely be applicable isolated supramolecular chemistry. In addition structural synthesis, applications summarized.
