Summary: Pillar[n]arenes typically form 1:1 host-guest complexes with guest molecules, but unique properties arise from the formation of new structures and the crystalline state. Cooperative binding of guest molecules to pillar[n]arene assemblies is crucial to achieve unique host-guest behavior. Moreover, planar chirality of pillar[n]arenes allows for chiral inversion, memory, and erasure, which is coupled with their host-guest properties. In this review, the diversity, functionality, and supramolecular chirality of host-guest pillar[n]arene assemblies are discussed.

Summary: The effective receptor 2 was achieved through the combination of three features: the high affinity of squaramides towards anions, cooperation in ion pair binding, and preorganization of the binding domains in the tripodal platform. This receptor showed selective extraction of extremely hydrated sulfate anions, overcoming the Hofmeister series, by forming an intramolecular network and changing into inorganic-organic associates in wet chloroform.

Summary: Paraquat (PQ) is an important pesticide in the field, but its high toxicity poses a threat to human health. A novel sensor molecule, TP5, has been designed to have better detection and removal efficiency for PQ through a synergistic effect. The TP5 showed sensitivity fluorescence response for PQ with a detection limit of 2.23 x 10(-7) M, and a test paper based on TP5 could detect PQ in water with an adsorption efficiency of up to 98.40%.

Summary: In this study, a highly integrated system was developed to consume intracellular glutathione (GSH) in cancer cells, thereby improving the therapeutic efficacy of chemo/photothermal treatment. Supramolecular prodrug self-assemblies (SPSAs) with IR825 loaded inside were used to consume GSH via two-pronged pathways. The released chlorambucil and the accompanied hyperthermia synergistically inhibited tumor growth.

Summary: This study reported highly efficient light-harvesting supramolecular assemblies based on TPE-4Py, SC4A-C6, and SP, which showed excellent ratiometric fluorescence signal output towards sulfites and displayed no obvious cytotoxicity to cells. The strategy not only resulted in a high-efficiency light-harvesting platform but also amplified the signal of the probe, making it an effective method for fabricating fluorescent cell sensors.

Summary: In this study, an artificial light-harvesting platform derived from pillararene-directed host-guest nanoparticles (WP53G) was developed. The platform exhibited a twostep FRET energy transfer from WP53G to eosin Y (ESY) and then to Nile red (NiR), resulting in a WP53G@ESY/NiR system with high efficiency. The system also showed tunable emission and demonstrated remarkable catalytic activity in the dehalogenation reaction in aqueous solution.

Summary: Directed strategy involving double cation-p interactions is used to prepare well-regulated Pt(II)-metallacycle-based 2D hierarchical self-assemblies. Arrays of planar Pt(II) metallacycles are spatially confined, and the growth of self-assemblies occurs at desired locations by employing strong cation-p driving forces as the second orthogonal NCI. The resulting 2D hierarchical self-assemblies are applied as dual-mode catalysis platforms.

Summary: Polyoxometalates (POMs) are utilized as alternative anode materials for lithium ion batteries (LIBs) due to their reversible electrochemical redox behaviors and electron storage functions. Embedding POMs into metal-organic hybrid complexes can enhance their conductivity and stability, and composite materials with graphene oxide show high initial specific capacity and stability for LIBs applications.

Summary: The study presents chiral assemblies with dual-stimuli responsiveness, consisting of planar-chiral pillar[5]arenes with azobenzene groups that undergo chiral amplification and collapse under thermo- and photostimuli control. The alignment of azobenzenes in the assemblies leads to chiral propagation and amplification, which can be switched on and off through trans to cis photoisomerization and cis to trans thermo-isomerization of the azobenzene groups.

Summary: Prostate cancer is a major health issue and the second most common cancer in men. Photodynamic therapy (PDT) is a non-invasive method that uses photosensitizers and light to induce cell death with minimal side effects. However, some photosensitizers used in PDT have low solubility in biological media, requiring functionalization or vectorization for effective internalization. This study used arene-ruthenium cages to deliver photosensitizers to prostate cancer cells. The results showed that most of the compounds induced cytotoxic effects on prostate cancer cells, with confirmed internalization in the cytoplasm. The presence of metals in the photosensitizers decreased the effectiveness of PDT, and in some cases, completely eliminated its effect.

Summary: The formation of pseudo[3]rotaxane assemblies by P4Q1 and H with bis-imidazolium and bis-pyridinium guests was established through NMR spectral analyses and high-resolution mass spectrometric analyses. The study thoroughly investigated the cooperativity in the formation of pseudo[3]rotaxane assemblies, with results indicating preferential 1:1 host-guest binding and positive cooperativity. The inclusion formation was facilitated by hydrogen bonding functional groups attached to the quinone motif of pillar[4]arene[1]quinone, resulting in the formation of pseudo[3]rotaxanes.

Summary: Host-guest complexation between decamethoxypillar[5]arene and difunctionalized pillar[4]arene[1]quinone with isatin was demonstrated by H-1 NMR titration experiments. The antibacterial activity of isatin, decamethoxypillar[5]arene, difunctionalized pillar[4]arene[1]quinone, and their isatin inclusion complexes against both Gram-positive and Gram-negative bacteria was assessed using the well-diffusion method. The results showed that decamethoxypillar[5]arene exhibited superior antibacterial activity compared to difunctionalized pillar[4]arene[1]quinone, and the isatin inclusion complex of decamethoxypillar[5]arene displayed excellent antibacterial activity similar to chloramphenicol against various bacteria.

Summary: In this study, MnCo2S4 nanosheet catalyst was successfully synthesized and found to exhibit superior performance in hydrogen evolution. Compared to MnCo2S4, MnCo2S4 showed low overpotentials, moderate Tafel slope, and excellent sustainability. The outstanding performance can be attributed to the increased number of electrochemically active sites and enhanced electronic conductivity on the catalyst surface.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
