In the mol-ecule of the title compound, [ZnCl(2)(C(9)H(9)N(3)S)(2)], the Zn(II) atom is four-coordinated by two N atoms from two 5-m-tolyl-1,3,4-thia-diazol-2-ylamine ligands and two Cl anions in a distorted tetra-hedral geometry. Intra-molecular N-H⋯N, N-H⋯Cl and C-H⋯S hydrogen bonds result in the formation of one planar and one non-planar five-membered, one non-planar six-membered and one non-planar seven-membered ring. The six- and seven-membered rings have twist conformations, while the non-planar five-membered ring adopts an envelope conformation with the S atom displaced by 0.541 (3) Å from the plane of the other ring atoms. The planar five-membered ring is oriented at dihedral angles of 1.74 (3) and 1.08 (3)°, respectively, with respect to the adjacent aromatic and thia-diazole rings. In the crystal structure, inter-molecular N-H⋯Cl hydrogen bonds link the mol-ecules into a three-dimensional network.

Determining the dissociation mechanism of perchlorate materials remains a top priority to address sustainability, handling, processing, and synthesis issues of new and existing high-energy density materials vital to many industrial processes. We determined the dissociation mechanism of diglycine perchlorate (DGPCl) using vibrational spectroscopy, which unveiled the formation of ammonium perchlorate (AP) and carbon at high temperatures. Our studies establish that DGPCl shows multiple phase transitions upon heating.

The ongoing soft actuation has accentuated the demand for dielectric elastomers (DEs) capable of large deformation to replace the traditional rigid mechanical apparatus. However, the low actuation strain of DEs considerably limits their practical applications. This work developed high-performance polyurethane-urea (PUU) elastomers featuring large actuation strains utilizing an approach of kinetic control over the microphase separation structure during the fabrication process.

Micronization is frequently employed to increase the dissolution of poorly soluble drugs, but it easily led to powder aggregation and difficult to mix well on the micro level with poor content uniformity and erratic dissolution behavior. Mannitol is the most commonly used pharmaceutical excipient, and its β form (β-mannitol) is commercially available and extensively investigated, whereas form α (α-mannitol) remain poorly understood. Here, this study demonstrated that α-mannitol could significantly eliminate aggregation phenomena of micronized drugs (i.

Intracellular delivery of proteins has attracted significant interest in biological research and cancer treatment, yet it continues to face challenges due to the lack of effective delivery approaches. Herein, we developed an efficient strategy cationic α-helical polypeptide-mediated anionic proprotein delivery. The protein was reversibly modified with adenosine triphosphate dynamic covalent chemistry to prepare an anionic proprotein (A-protein) with abundant phosphate groups.

In recent years, visible light-induced ligand-to-metal charge transfer (LMCT) has emerged as an attractive approach for synthesizing a range of functionalized molecules. Compared to conventional photoredox reactions, photoinduced LMCT activation does not depend on redox potential and offers diverse reaction pathways, making it particularly suitable for the activation of inert bonds and the functional modification of complex organic molecules. This review highlights the indispensable role of photoinduced LMCT in synthetic chemistry, with a focus on recent advancements in LMCT-mediated hydrogen atom transfer (HAT), C-C bond cleavage, decarboxylative transformations, and radical ligand transfer (RLT) reactions.
