“…Coordination-driven self-assembly is a powerful tool to construct metal–organic cages (MOCs) with well-defined cavities. − MOCs serve as suitable hosts featuring dynamic cavities that are similar to enzyme-binding pockets, which can encapsulate one or several guest molecules. MOCs exhibit multiple potential applications, such as molecular recognition and sensing, − molecular separation, , drug delivery, − stabilizing reactive species, , catalysis, − etc. A gigantic number of MOCs with varied structures have been fabricated.…”

Herein we report two tubular metal−organic cages (MOCs), synthesized by the self-assembly of bidentate metalloligands with different lengths and Pd II . These two MOCs feature Pd 4 L 8 -type square tubular and Pd 3 L 6 -type triangular cage structures, respectively. Both MOCs have been fully characterized by NMR spectroscopy, mass spectrometry, and theoretical calculation. Both cages can be employed for encapsulating polycyclic aromatic hydrocarbons and show high binding affinity toward coronene.

Industrial activity has raised significant concerns regarding the widespread pollution caused by metal ions, contaminating ecosystems and causing adverse effects on human health. Therefore, the development of sensors for selective and sensitive detection of these analytes is extremely important. In this regard, an azo dye, Dabcyl 2, was synthesised and investigated for sensing metal ions with environmental and industrial relevance. The cation binding character of 2 was evaluated by colour changes as seen by the naked eye, UV-Vis and 1H NMR titrations in aqueous mixtures of SDS (0.02 M, pH 6) solution with acetonitrile (99:1, v/v). Out of the several cations tested, chemosensor 2 had a selective response for Pd2+, Sn2+ and Fe3+, showing a remarkable colour change visible to the naked eye and large bathochromic shifts in the UV-Vis spectrum of 2. This compound was very sensitive for Pd2+, Sn2+ and Fe3+, with a detection limit as low as 5.4 × 10−8 M, 1.3 × 10−7 M and 5.2 × 10−8 M, respectively. Moreover, comparative studies revealed that chemosensor 2 had high selectivity towards Pd2+ even in the presence of other metal ions in SDS aqueous mixtures.

Homochiral metalated tetraphenylethylene‐based organic cages: Unusual chiral and luminescent behavior depending on thermodynamic and kinetic aggregation

Chirality and luminescence are important for both chemistry and biology, which are highly influenced by aggregation. In this work, a pair of metalated tetraphenylethylene(TPE)‐based organic cage enantiomers are reported, which feature a quadrangular prismatic cage structure. These homochiral cages exhibit concentration‐dependent chiral behaviors alongside a propensity for thermodynamic aggregation. Aggregation caused quench effect is found for these cages accompanying the increasing of the concentrations. When a poor solvent is added to produce a kinetical aggregation, the aggregation‐annihilation circular dichroism and aggregation‐induced emission behaviors are observed for these enantiomeric cages. By comparing these observations with the photophysical behaviors of a pair of structurally similar organic molecular enantiomers, the unique photophysical properties observed are intricately linked to the metal‐integrated TPE‐functionalized cage structures.
