Chiral Tin-Oxo Cluster Matrices with Fluorophore Embedment for Multichromatic Circularly Polarized Luminescence.

Tin-oxo clusters, characterized by their well-defined chemical compositions and architectures, are multi-metal aggregates composed of Sn-oxide cores and surface ligands. Chirality, a fundamental characteristic governing biological recognition and signal transduction, remains underexplored in stannate clusters compared to extensively studied precious metal clusters. Herein, three enantiomeric pairs of chiral tin-oxo clusters were constructed using axially chiral 1,1'-bi-2-naphthol (BINOL) ligands.

Organotin-Oxo Clusters with Enhanced π-Conjugation for Iodine Capture.

The sustainable development of nuclear energy raises significant challenges in handling radioactive iodine (I). Tin-oxo clusters are multimetal aggregates composed of Sn-oxide motifs and surface ligands. Sn ions have a strong affinity for iodine, making tin-oxo clusters promising candidates for trapping I.

Superhydrophobic Pseudosupertetrahedral Sulfido Metalate Clusters for Constructing Liquid Marbles.

One pseudopentasupertetrahedral chalcogenidometalate cluster, [(BuSn)SnCdS(OH)]·6(HDMP) (PPS-1; HDMP = protonated 3,5-dimethylpiperidine), has been isolated by use of an organotin precursor. They are arranged to generate two types of tetrahedrally patterned cages, which further interconnect to form a diamond network. Owing to the covalent attachment of abundant alkyl groups, PPS-1 exhibits excellent hydrophobicity and could be used as an assembly substance for building liquid marbles.

High-throughput discovery of chloroplast and mitochondrial DNA polymorphisms in Brassicaceae species by ORG-EcoTILLING.

Background: Information on polymorphic DNA in organelle genomes is essential for evolutionary and ecological studies. However, it is challenging to perform high-throughput investigations of chloroplast and mitochondrial DNA polymorphisms. In recent years, EcoTILLING stands out as one of the most universal, low-cost, and high-throughput reverse genetic methods, and the identification of natural genetic variants can provide much information about gene function, association mapping and linkage disequilibrium analysis and species evolution.
