Recently zero-dimensional (0-D) inorganic-organic metal halides (IOMHs) have become a promising class of optoelectronic materials. Herein, we report a new photoluminescent (PL) 0-D antimony(III)-based IOMH single crystal, namely [HBPZ][SbCl]·HO (BPZ = benzylpiperazine). Photophysical characterizations indicate that [HBPZ][SbCl]·HO exhibits singlet/triplet dual-band emission.

- Zero-dimensional organic-inorganic metal halides (OIMHs), particularly hybrid antimony(III) bromides (HABs), have potential for high photoluminescence quantum yields (PLQYs), but current values are lower compared to their chloride counterparts.* -
- Researchers developed a method to enhance PLQYs by synthesizing two structurally similar HABs with different solvent molecules, resulting in notable differences in their emission properties and PLQYs, specifically a nearly twofold increase in PLQY for one compound.* -
- The improvement in PLQY is linked to structural changes influenced by hydrogen bonding between the inorganic components and solvent molecules, underscoring the importance of structural rigidity in optimizing the phot
Article Synopsis
- The study focuses on the importance of radiocesium remediation for ecological safety, human health, and sustainable nuclear energy development.
- Researchers have developed a robust material, KInSnS (InSnS-1), which effectively captures cesium (Cs) from strongly acidic solutions, overcoming challenges related to material stability and competition from protons.
- The material not only has a high capacity for Cs adsorption but also serves in ion exchange processes; its selective adsorption mechanisms have been analyzed using single-crystal structure techniques.
Article Synopsis
- The compound [Cmim][Mim][SbCl] features dual cations and is the first to demonstrate deep-red emission in zero-dimensional organic-inorganic hybrid materials.
- The emission is attributed to significant anion distortion caused by imbalanced supramolecular interactions.
- This results in a remarkably large Stokes shift of 335 nm and a full width at half maximum (FWHM) of 210 nm in the emission spectrum.
Article Synopsis
- Zero-dimensional metal halides, particularly [EtPPh][SbCl], are gaining interest for their ability to switch luminescence, making them useful for sensors and anticounterfeiting.
- Research showed that only solvent molecules with a volume less than 22.3 Å can interact with [EtPPh][SbCl], influencing their photoluminescent properties.
- The study further revealed that solvent functional groups affect the hydrogen bonding strength with [SbCl], leading to changes in luminescent behavior and enhancing overall photoluminescence quantum yield to 95%.
Although luminescent indium(III) based halide perovskites have been widely investigated, the study of emissive indium(III) halide hybrids is limited. Three indium(III) chloride hybrids based on a bpym ligand were synthesized, namely [EPy][InCl(bpym)InCl]·DMF (1), [EPy][InCl(bpym)InCl] (2), and [BPy][InCl(bpym)InCl] (3) (EPy = -ethylpyridinium; BPy = -butylpyridinium; bpym = 2,2'-bipyrimidine). They all exhibit a zero-dimensional structure, in which the ligand bpym interconnects two [InCl] to form a [InCl(bpym)InCl] anion that is further charge-compensated by the corresponding pyridinium cations.

Herein we report a lead-free 0D-OIMH compound, namely [Emim]8[SbCl6]2[SbCl5] (1, Emim = 1-ethyl-3-methylimidazolium), which is the first crystal containing two distinct mononuclear [SbXn]3-n units in one single structure. The optical absorption, temperature/excitation-variable photoluminescence (PL) and PL decay were studied.

Herein, the rapid and selective removal of Cs, Sr, and Eu ions is achieved by two metal sulfides (FJSM-SnS-2 and FJSM-SnS-3). Both structures feature [SnS] layers with the mixed cations of [CHNH] and [Bmmim] (1-butyl-2,3-dimethylimidazolium) as templates.

The systematical clarification for underlying mechanism of Cs removal and elution at the molecular level is rare. Here, efficient Cs capture is achieved by a thioantimonate [MeNH]SbS (FJSM-SbS) with high capacity, fast kinetics, wide pH durability, excellent β and γ radiation resistances, and facile elution.

Structural comparison reveals that and possess similar anionic zigzaglike chain of [BiCl(bpym)]; however, different packing modes of anion/cations and thus different weak interactions. Interestingly, the utilization of pyridinium cations with different length of alkyl chain could tune the RTP behaviors efficiently.
