The title compounds, CHOSi () and CHOSi (), are classified as di-hydro-furylsilanes, which show great potential as building blocks for various functionalized silanes. They both crystallize in the space group in the triclinic crystal system. Analyses of the Hirshfeld surfaces show packing-determining inter-actions for both compounds, resulting in a polymeric chain along the [011] for silane and a layered-inter-connected structure along the -axis direction for silane .

The reactions of LAlH (L = HC(CMeNAr), Ar = 2,6-PrCH) (1) with diphenylphosphane oxide [PhP(O)H], diphenylphosphinamide [PhP(O)NH], and diaryl/alkyl phosphane [(RO)P(O)H (R = Ph, or Pr)] afford their corresponding compounds with compositions LAl(H)OP(Ph) (2), LAl[OP(Ph)] (3), LAl{[N(H)P(O)(Ph)][OP(Ph)]} (4), LAl(OPr) (5), and LAl(OPh) (6), respectively. These reactions probably undergo a process of dehydrogenation coupling, deaminating dehydrogenation coupling, or chain-breaking coupling. It is noteworthy to mention that the reaction of compound 1 with 2 equiv.

A new diterpenoid, carneadiol (1), with an unprecedented tricyclic carbon skeleton, was isolated from the culture extracts of Nocardia carnea IFM 12324. The structure of compound 1 was elucidated using spectral studies, including various NMR data. The absolute configuration of 1 was determined using X-ray crystallographic analysis with the crystalline sponge method.

Finding ways to produce dense and smooth perovskite films with negligible defects is vital for achieving high-efficiency perovskite solar cells (PSCs). Herein, we aim to enhance the quality of the perovskite films through the utilization of a multifunctional additive in the perovskite anti-solvent, a strategy referred to as anti-solvent additive engineering. Specifically, we introduce ortho-substituted-4'-(4,4″-di-tert-butyl-1,1':3',1″-terphenyl)-graphdiyne (o-TB-GDY) as an AAE additive, characterized by its sp/sp-cohybridized and highly π-conjugated structure, into the anti-solvent.

ConspectusSymmetry is a pervasive phenomenon spanning diverse fields, from art and architecture to mathematics and science. In the scientific realms, symmetry reveals fundamental laws, while symmetry breaking─the collapse of certain symmetry─is the underlying cause of phenomena. Research on symmetry and symmetry breaking consistently provides valuable insights across disciplines, from parity violation in physics to the origin of homochirality in biology.

Topological edge states (TESs) and topological corner states (TCSs) in photonic crystals (PCs) provide an effective way to control the propagation and localization of light. The topological performance of integrated photonic devices can be improved by introducing the basic structural unit of photonic quasicrystals (PQCs) into PCs. However, the previous works arranged the basic structural unit of Stampfli-type and 12-fold Penrose-type photonic quasicrystals into triangular lattices, which have a complex structure and allow light to only propagate around 60° or 120° corners, limiting their applications.
