Cyclometalated -Difluoromethylbenzimidazolylidene Platinum(II) Complexes with Built-in Secondary Coordination Spheres: Photophysical Properties and Bioimaging.

Bidentate Pt(II) complexes with cyclometalated -heteroarene or -heterocyclic carbene (NHC) ligands have been extensively studied as phosphorescent emitters over the past two decades. Herein, we introduce a difluoromethyl group (CFH) into the wingtip of NHCs, where CFH acts as a lipophilic hydrogen bond (HB) donor. Their cyclometalated Pt(II) complexes show excellent PLQYs (up to 93%) and phosphorescence lifetimes mainly due to the rigid structure with hydrogen bonding between the CFH group and the adjacent O atom at the β-diketonate ligand.

Influence paradigms of soil moisture on land surface energy partitioning under different climatic conditions.

Soil moisture (SM) directly controls the land surface energy partition which plays an important role in the formation of extreme weather events. However, its dependence on specific climatic conditions is not thoroughly understood due to the complexity of soil moisture effects. Here, we examine the relationship between SM and surface energy partitioning under different climate conditions, and identify the influence paradigms of soil moisture on surface energy partition.

Biodegradable active composite hydrogel packaging for postharvest climacteric bananas preservation.

Boron-based PdB alloy cluster as a nanoscale antifriction bearing system: tubular core-shell structure, double π/σ aromaticity, and dynamic structural fluxionality.

Boron-based nanoclusters show unique geometric structures, nonclassical chemical bonding, and dynamic structural fluxionality. We report here on the theoretical prediction of a binary PdB cluster, which is composed of a triangular Pd core and a tubular double-ring B unit in a coaxial fashion, as identified through global structural searches and electronic structure calculations. Molecular dynamics simulations indicate that in the core-shell alloy cluster, the B double-ring unit can rotate freely around its Pd core at room temperature and beyond.

Invasion risks presented by Gonopsis affinis and the use of Trissolcus mitsukurii as a biological control agent under present and future climate conditions.

Background: Gonopsis affinis (Uhler) is a stinkbug that represents a significant threat to the production of rice (Oryza sativa L.), sugarcane (Saccharum officinarum L.) and eulalia (Miscanthus sinensis (Andersson)), and has been listed as a sugarcane pest in Japan.

Ternary XBeH (X = Si, Ge, Sn, Pb) Clusters: Planar Tetracoordinate Si/Ge/Sn/Pb Species with 18 Valence Electrons.

As one of the important probes of chemical bonding, planar tetracoordinate carbon (ptC) compounds have been receiving much attention. Compared with ptC clusters, the heavier planar tetracoordinate silicon, germanium, tin, lead (ptSi/Ge/Sn/Pb) systems are scarcer and more exotic. The 18-valence-electron (ve)-counting is one important guide, though not the only rule, for the design of planar tetra-, penta-coordinate carbon and silicon clusters.

A water-soluble fluorescent pH probe and its application for monitoring lysosomal pH changes in living cells.

Intracellular pH plays a crucial role in many cellular processes, and abnormal intracellular pH has been linked to common diseases such as cancer and Alzheimer's. To address this issue, a water-soluble fluorescent pH probe was designed based on the protonation/deprotonation of the 4-methylpiperazin-1-yl group, using dicyanoisophorone as the fluorophore. In the neutral form of the probe, fluorescence is quenched due to charge transfer from the 4-methylpiperazin-1-yl group to the fluorophore upon excitation.

Long-term deposition of fly ash regulates bacterial communities in different disturbance zones: Evidence from diversity, network complexity and predictive metabolic function.

The structural diversity and metabolic pathways formed by soil microbial-environmental factor interactions can be used to predict the differences in microbial ecological functions. The storage of fly ash (FA) has caused potential harm to the surrounding soil environment, whereas little is known about bacterial communities and environmental factor interactions in FA-disturbed areas. In this study, we selected two disturbed areas (DW: dry-wet deposition zone, LF: leachate flow zone) and two nondisturbed areas (CSO: control point soil, CSE: control point sediment) as the test areas and used high-throughput sequencing technology to investigate the bacterial communities.

Sc@B, Ti@B, V@B, and V@B: Spherically Aromatic Endohedral Seashell-like Metallo-Borospherenes.

Transition-metal-doped boron nanoclusters exhibit unique structures and bonding in chemistry. Using the experimentally observed seashell-like borospherenes B and B as ligands and based on extensive first-principles theory calculations, we predict herein a series of novel transition-metal-centered endohedral seashell-like metallo-borospherenes Sc@B (), Ti@B (), V@B (), and V@B () which, as the global minima of the complex systems, turn out to be the boron analogues of dibenzenechromium Cr(CH) with two B ligands on the top and bottom interconnected by four or five corner boron atoms on the waist and one transition-metal "pearl" sandwiched at the center in between. Detailed molecular orbital, adaptive natural density partitioning (AdNDP), and iso-chemical shielding surface (ICSS) analyses indicate that, similar to Cr(CH), these endohedral seashell-like complexes follow the 18-electron rule in bonding patterns (1S1P1D), rendering spherical aromaticity and extra stability to the systems.

A near-infrared fluorescent probe for imaging of SO flux in drug-induced liver injury.

Sulfur dioxide (SO) has been widely applied as an important additive in various foods and drugs due to its antioxidant, antiseptic and bleaching properties. SO in living organisms plays a key biological role as an antioxidant in a variety of life activities. However, abnormal levels of SO in both food and living organisms could cause harm and even serious illness, such as diseases related to the respiratory and cardiovascular systems and cancers.

Chemical Bonding and Dynamic Structural Fluxionality of a Boron-Based NaB Sandwich Cluster.

Doping alkali metals into boron clusters can effectively compensate for the intrinsic electron deficiency of boron and lead to interesting boron-based binary clusters, owing to the small electronegativity of the former elements. We report on the computational design of a three-layered sandwich cluster, NaB, on the basis of global-minimum (GM) searches and electronic structure calculations. It is shown that the NaB cluster can be described as a charge-transfer complex: [Na][B][Na].
