Organic-inorganic hybrid materials built by inorganic and organic building units have attracted intensive interest in the past decades due to unique chemical and physical properties. However, rare organic-inorganic hybrid materials show excellent permanent magnetic properties. Here, we develop a facile chemical solution method to bottom-up synthesize a new hybrid (FeSe)[Fe(dien)]. This hybrid phase with the space group (14) possesses a rodlike shape with a diameter of 100-2000 nm and a length of 5-50 µm. The hybrid rods are ferrimagnetic with a Curie temperature () of 11 K. They show a high coercivity () of 4.67 kOe and a saturation magnetization () of 13.5 emu/g at 2 K. Compared with orthorhombic (FeSe)Fe(dien), the excellent magnetic performance of the hybrid rods is ascribed to the monoclinic hybrid structure built by Fe(dien) complexes and FeSe double chains. Our study provides guidance for connecting inorganic fragments of FeSe single chains, FeSe double chains or β-FeSe layers with Fe(dien) complexes for organic-inorganic hybrid phases with varied crystal structures and magnetic properties.

The hybrid magnetic heterostructures and superlattices, composed of organic and inorganic materials, have shown great potential for quantum computing and next-generation information technology. Organic materials generally possess designable structural motifs and versatile optical, electronic, and magnetic properties, but are too delicate for robust integration into solid-state devices. In contrast, inorganic systems provide robust solid-state interface and excellent electronic properties but with limited customization space.

Lithium (Li) metal's extremely high specific energy and low potential make it critical for high-performance batteries. However, uncontrolled dendrite growth and an unstable solid-electrolyte interphase (SEI) during repeated cycling still seriously hinder its practical application in Li metal batteries. Herein, we demonstrate a facile and effective approach to fabricate a flexible and robust hybrid SEI layer using two kinds of organo-polysulfides with different sulfur chain lengths [bis(3-(triethoxysilyl)propyl)disulfide (Si-O-2S) and bis(3-(triethoxysilyl)propyl)tetrasulfide (Si-O-4S)] as the additives in the electrolyte.

Cathode materials with both high capacity and high operating voltage are essential for advancing aqueous zinc-ion batteries (ZIBs). Conventional high-capacity materials, such as vanadium-based compounds, typically deliver low discharge voltages. In contrast, organic cathodes show high operating voltages but often exhibit limited capacity.

Ternary copper halides with an eco-friendly property have emerged as attractive candidates to replace toxic lead-containing perovskites for light-emitting diodes (LEDs), yet achieving long-wavelength electroluminescence remains unexplored. Herein, we report the first realization of orange-emitting LEDs (595 nm) based on nontoxic organic-inorganic PEACuI (PEA = β-phenylethylamine) films enabled by a nonionic surfactant poly(propylene glycol) bis(2-aminopropyl ether) (APPG) chemisorption. Experimental and theoretical analyses rationalize that the APPG additive has strong chemisorption with the Cu-I framework within the grain boundaries of PEACuI films, which not only improves the film's morphology but also passivates the iodine vacancy defects.

Efficient room-temperature sensors for toxic gases are essential to ensure a safe and healthy life. Conducting frameworks have shown great promise in advancing gas sensing technologies. In this study, two new organic-inorganic frameworks [CuX(PPh)(L)], CP1 (X = I) and CP2 (X = Br) have been synthesized using (pyridin-4-yl)-N-(4H-1,2,4-triazol-4-yl)methanimine (L) and triphenylphosphine.
