Article Synopsis
- Chiral Pb-free metal-halide semiconductors (MHSs) are gaining interest in spintronics for their unique spin properties and the chiral-induced spin selectivity (CISS) effect, but most known chiral MHSs have limited structures.
- This study introduces a new class of chiral MHSs based on palladium (Pd) with 1D square-pyramidal and 0D square-planar configurations, resulting in a general formula that reflects their structural diversity.
- The research shows a successful transfer of chirality from organic components to the inorganic Pd-halides, revealing a high distortion index and demonstrating potential for these materials in future spintronic applications.
Article Synopsis
- The study focuses on solid-state structural transformation for creating metal-organic frameworks (MOFs), which are often difficult to synthesize through direct methods.
- The researchers synthesized two unique photoreactive binuclear Zn(II) MOFs that differ in their structural frameworks and demonstrated varying degrees of photoreaction upon UV light exposure.
- This light-induced transformation successfully converted lower-dimensional MOFs into higher-dimensional structures, showcasing the potential of solid-state [2 + 2] photoreactions for post-synthetic modifications.
Chiral metal-organic frameworks (CMOFs) and solid-state [2 + 2] photocyclization have been explored as independent areas in crystal engineering. We herein report the photoreactive CMOFs that undergo a [2 + 2] photocycloaddition reaction for the first time. Through the incorporation of a dipyridyl olefin ligand, 1,4-bis[2-(4-pyridyl)ethenyl]benzene, and d-camphoric acid or l-camphoric acid, we constructed a pair of homochiral Zn(II) CMOFs (d- or l-) with a two-dimensional sql topology via a two-step procedure to avoid racemization.
