Abstract Making oppositely charged metal‐organic cages (MOCs) into a tightly ordered structure may bring interesting functions. Herein, we report novel composed of anionic (Zr 4 L 6 ) 8− (L=embonate) tetrahedral and in situ‐formed cationic [Zn (Bim) ] 4+ (Bim=[BH(im) 3 − ; im=imidazole) cubic cages. Chiral transfer is observed from enantiopure cage to cage. A pair enantiomers (PTC‐373(Δ) PTC‐373(Λ)) are formed. PTC‐373 exhibits high chemical thermal stabilities, affording an single‐crystal‐to‐single‐crystal transformation. More importantly, the combination ionic significantly enhances its third‐order nonlinear optical property, thin‐film excellent limiting effect.

Molecular hosts with functional cavities can emulate enzymatic behavior through selective encapsulation of substrates, resulting in high chemo-, regio-, and stereoselective product formation. It is still challenging to synthesize enzyme-mimicking that exhibit a narrow substrate scope relies upon the recognition substrates based on molecular size. Herein, we introduce Pd

The concept of pore space partition has emerged as an effective strategy for developing improved coordination-based supramolecular porous materials with exceptional performance. Herein, we report that a water-soluble self-assembled tetrahedral cage 1 partitioned cavity shown excellent performance multifunctional extractant. results show this unique can efficiently separate halogenated adamantanes, adamantane isomers, and polycyclic aromatic hydrocarbons. Furthermore, the influence cavity-partitioned on electrochemical properties redox-active molecules electrochemically driven reversible host-guest process also been demonstrated. findings offer valuable insights into design development new type controlled phase separation tailored properties.

Received: 19 September 2024; Revised: 12 October Accepted: 25 Published: November 2024 Abstract: Researchers worldwide are developing innovative luminescent systems with exceptional features like high sensitivity. frameworks based on aggregation-induced emission (AIE) have emerged as promising candidates various applications. Over the past decade, porous materials metal-organic cages (MOCs) incorporating AIE luminogens (AIEgens) demonstrated performance. Chirality plays a significant role specific non-racemic systems, particularly circularly polarized luminescence (CPL). Chiral organic coordinated metals, including MOCs, gained importance they combine ligands coordination-bonded metal centers, enabling design novel structures CPL. These shown exciting potential applications fields CPL-OLED, chiral recognition, sensing. This review article provides an overview recent progress emissive materials, specifically their possible Additionally, focuses AIEgen-based cages, CPL-active non-AIEgen-based practical sensing enantioselectivity, future prospects.

Circular trinuclear helicates have been synthesized from a bis-biphenol strand (LH4), titanium isopropoxide, and various diimine ligands. These self-assembled architectures constructed around three TiO4N2 nodes heterochiral structure (C1 symmetry) when 2,2′-bipyridine (A), 4,4′-dimethyl-2,2′-bipyridine (B), 4,4′-bromo-2,2′-bipyridine (C), or 4,4′-dimethyl-2,2′-bipyrimidine (D) is employed. Within these complexes, one nitrogen ligand endo-positioned inside the metallo-macrocycle, whereas other two ligands point outside helicate framework. This investigation highlights that which does not participate in framework of complex controls overall symmetry since 2,2′-bipyrimidine chelate (F) ends formation homochiral aggregate (C3 symmetry). The lack found solid state for species ([Ti3L3(B)3], [Ti3L3(C)3], [Ti3L3(D)3]) observed complexes solution (dichloromethane chloroform).
