Zero-dimensional (0D) metal halides with solid-state luminescence switching (SSLS) have attracted attention as sensors and luminescent anticounterfeiting. Herein, selective solvent molecule response accordingly were discovered in 0D [EtPPh3]2[SbCl5] (1, EtPPh3 = ethyltriphenylphosphonium). More than a dozen kinds of molecules been tested to find out the selection rule for absorption 1, which is demonstrated be size effect guest molecules. Confirmed by crystal structural analysis, only...
Abstract In recent decades, white light‐emitting diodes (WLEDs) assembled by blue (LEDs) and down‐conversion phosphors have gained rapid development. Thereinto, red phosphors, especially for the ecofriendly cost‐effective ones, serve an important role preparation of superior WLEDs. Herein, a halide compound with 0D crystal structure, namely [PPh 4 ] 2 [Bi Br 8 (bp4do)(DMSO) ( BiBrON , PPh = tetraphenylphosphonium, bp4do 4,4′‐bipyridine 1,1′‐dioxide, DMSO dimethyl sulfoxide) is synthesized at...
Zero-dimensional (0D) organic–inorganic metal halides (OIMHs) have attracted tremendous attention due to their fascinating optoelectronic properties. Herein, we report an antimony(III)-based 0D OIMH of [PPh3H]2[SbCl5] comprising discrete [SbCl5]2– pyramids and protonated triphenylphosphine (PPh3H) cations with a low charge density. Abundant supramolecular interactions including C–H···Cl rare P–H···Cl hydrogen bonds C–H···Π anion···Π lead three-dimensional (3D) framework structure...
Zero-dimensional (0D) organic-inorganic metal halides (OIMHs) hold promise in photoluminescence properties and related applications. Thus far, the quantum yields (PLQYs) of reported 0D hybrid antimony(III) bromides (HABs) are not as high those chloride analogs; therefore, improvement PLQY is an important issue for luminescent HABs. Herein, a supramolecular interaction adjustment strategy to improve PLQYs HABs proposed. Two isostructural that crystallize with different lattice solvent...
Recently zero-dimensional (0-D) inorganic–organic metal halides (IOMHs) have become a promising class of optoelectronic materials. Herein, we report new photoluminescent (PL) 0-D antimony(III)-based IOMH single crystal, namely [H2BPZ][SbCl5]·H2O (BPZ = benzylpiperazine). Photophysical characterizations indicate that exhibits singlet/triplet dual-band emission. Density functional theory (DFT) calculations suggest has the large energy difference between singlet and triplet states, which might...
Vacancy-ordered perovskites and derivatives represent an important subclass of hybrid metal halides with promise in applications including light emitting devices photovoltaics. Understanding the vacancy-property relationship is crucial for designing related task-specific materials, yet research this field remains sporadic. For first time, we use Connolly surface to quantitatively calculate volume vacancy (V□, □=vacancy) vacancy-ordered double perovskite (VDPDs). A between void fraction...
In recent years, inorganic-organic hybrid metal halides (IOMHs) have attracted wide attention in the field of white light-emitting diodes (WLEDs) due to their advantages high-efficiency broadband emission, high photoluminescence...
Compound [C5mim][Mim]2[SbCl6] (1; [C5mim]+ = 1-pentyl-3-methylimidazolium; [Mim]+ N-methylimidazolium) with dual cations exhibits the first case of deep-red emission in [SbCl6]3--based 0D OIMHs. Anion distortion due to high disequilibrium supramolecular interactions is revealed be responsible for extremely large Stokes shift 335 nm and FWHM 210 emission.
Bismuth-halide-based inorganic-organic hybrid materials (Bi-IOHMs) are desirable in luminescence-related applications due to their advantages such as low toxicity and chemical stability. Herein, two Bi-IOHMs of [Bpy][BiCl4(Phen)] (1, Bpy = N-butylpyridinium, Phen 1,10-phenanthroline) [PP14][BiCl4(Phen)]·0.25H2O (2, PP14 N-butyl-N-methylpiperidinium), containing different ionic liquid cations same anionic units, have been synthesized characterized. Single-crystal X-ray diffraction reveals...
X-ray scintillation and cyan phosphorescence are observed for three isomorphic ionic bismuth halides.
The plentiful structural features and excellent fluorescence properties of lanthanide coordination polymers (Ln-CPs) have garnered much attention in recent years. Herein, 1,4-naphthalic acid (1,4-NDCH2) has been used to assemble a series Eu-CPs formulated as [Eu2(1,4-NDC)3(DMF)(H2O)] (1-Eu), [Eu2(1,4-NDC)3(DMF)] (2-Eu), [Eu2(1,4-NDC)3(DMF)4]·DMF (3-Eu). Single-crystal structure analyses reveal that 1-Eu 2-Eu feature three-dimensional (3D) structures with 3-nodal net an oab topology,...
Although luminescent indium(III) based halide perovskites have been widely investigated, the study of emissive hybrids is limited. Three chloride on a bpym ligand were synthesized, namely [EPy]2[InCl4(bpym)InCl4]·DMF (1), [EPy]2[InCl4(bpym)InCl4] (2), and [BPy]2[InCl4(bpym)InCl4] (3) (EPy = N-ethylpyridinium; BPy N-butylpyridinium; 2,2'-bipyrimidine). They all exhibit zero-dimensional structure, in which interconnects two [InCl4]- to form [InCl4(bpym)InCl4]2- anion that further...
