The ability to collectively program chiral recognition and the hierarchical self-assembly of molecular supramolecular building blocks into complex higher-order superstructures is a significant goal in chemistry. Metal-organic cages are excellent model systems examine self-sorting build self-assembly. Herein, details on how limiting conformational flexibility incorporating hydrogen bonding functional groups ligands can influence metal-organic reported. urea-functionalized axially bis-pyridyl...
Herein, we report the self‐assembly and chiroptical properties of two axially chiral π‐conjugated luminogens, R‐NMI S‐NMI, each equipped with pyridyl moieties for hydrogen (H)‐bonding diacids. The enantiomers display aggregation‐induced emission enhancement (AIEE) increased CD CPL signals in self‐assembled state a high glum value 1.5 (±0.06) × 10‐2 1:9 dioxane:methylcyclohexane. Crystallographic analysis confirmed mirror‐image helical structures S‐NMI involving both intra‐ intermolecular π‐π...

When a racemic mixture of chiral building blocks self-assembles to form discrete molecular or supramolecular cages, the system can adopt either social narcissistic self-sorting. However, control over such self-sorting is hard achieve with desired choice outcome. Herein, we report anion templated high-fidelity during coordination-driven self-assembly [Pd2 L4 ] metal-organic an axially ligand. Upon varying counter-anions, outcome self-sorting, whether narcissistic, leading kinetically favored...
Chiral self-sorting during the formation of cage-like molecules continues to fascinate and advance our understanding phenomenon in general. Herein, we report chiral Pd6 L12 -type metal-organic cages. When a racemic mixture axially bis-pyridyl ligands undergo coordination-driven self-assembly with Pd(II) ions form cages, system has option afford any at least 70 pairs (one homochiral 69 heterochiral) enantiomers 5 meso isomers or statistical everything. However, resulted diastereoselective...
The design and synthesis of a cleft-shaped bis-diarylurea receptor for chloride anion transport is reported in this work. based on the foldameric nature N,N'-diphenylurea upon its dimethylation. exhibits strong selective affinity over bromide iodide anions. A nanomolar quantity efficiently transports across lipid bilayer membrane as 1:1 complex (EC50 = 5.23 nm). work demonstrates utility N,N'-dimethyl-N,N'-diphenylurea scaffold recognition transport.
Metal-organic frameworks (MOFs) constructed with cavity-containing inherently porous organic cage linkers are rare. Among these, none have provided structural evidence of guest molecules being hosted inside the linkers. Such materials highly desirable for trapping carcinogenic polycyclic aromatic hydrocarbons (PAHs) from water, which remains challenging existing adsorbents. Herein, we present first example a metal-“organic cage” framework encapsulated within MOF. We utilize triazole-equipped...
Abstract Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic and persistent organic pollutants in water. Their removal is highly challenging for existing generic nonspecific adsorbents, creating an urgent need tailored solutions. Herein, a metal‐“organic cage” framework, MOF‐CC‐1 , designed the effective scavenging of PAHs from water introduced. This framework constructed using propeller‐shaped cofacial cage ( CC‐1 ), equipped with three triazole pillars that coordinate Ag(I) ions. The...
We report the design and synthesis of a new cleft-shaped bis-urea receptor for recognition tetrahedral oxyanions from foldameric N,N′-dimethyl-N,N′-diphenylurea scaffold. The forms 3:1 host–guest complexes with sulfate, phosphate, arsenate anions in solid state by readily binding them through hydrogen bonding. 1H NMR analysis events competitive medium (DMSO-d6/H2O, 90:10) revealed that has strong selective affinity (Ka(3:1) = 2.41 (±0.79) × 108 M–3) comparison phosphate no sulfate. extracts...
