Guest-Molecule-Induced Glass-Crystal Transition in Organic-Inorganic Hybrid Antimony Halides.

The glassy state of inorganic-organic hybrid metal halides combines their excellent optoelectronic properties with the outstanding processability of glass, showcasing unique application potential in solar devices, display technologies, and plastic electronics. Herein, by tailoring the organic cation from -phenylpiperazine to dimethylamine gradually, four types of zero-dimensional antimony halides are obtained with various optical and thermal properties. The guest water molecules in crystal (-phenylpiperazine)SbCl·Cl·5HO lead to the largest distortion of the Sb-halogen unit, resulting in the red emission different from the yellow emission of other compounds.

Organic Ligand Exchange: The Chiral Structure-Property Regulation of Cuprous Halides.

The strategy of organic ligand exchange is proposed to tune the optical properties of organic-inorganic hybrid cuprous halides. In this work, the chiral ligand (S)-(-)-2,2'-bis(di--tolylphosphino)-1,1'-binaphthyl ((S)-Tol-BINAP) and achiral triphenylphosphine (PPh) are introduced into cuprous halides CuX-PPh-[(S)-Tol-BINAP] (X = Cl, Br, I) through organic ligand exchange. As a result, the mixed organic ligands can enhance second harmonic generation (SHG) and aggregation-induced emission (AIE) optical properties.

Lead-based two-dimensional organic-inorganic hybrid perovskites (2D HOIPs) are popular materials with various optical properties, which can be tuned through metal ion doping.

From HCNCdI to HCNCdI: a highly polarizable CdNI tetrahedron induced a sharp enhancement of second harmonic generation response and birefringence.

In this study, we identify a novel class of second-order nonlinear optical (NLO) crystals, non-π-conjugated piperazine (HCN, PIP) metal halides, represented by two centimeter-sized, noncentrosymmetric organic-inorganic metal halides (OIMHs), namely HCNCdI (222) and HCNCdI (). HCNCdI is the first to be prepared, and its structure contains a CdI tetrahedron, which led to a poor NLO performance, including a weak and non-phase-matchable second harmonic generation (SHG) response of 0.5 × KHPO (KDP), a small birefringence of 0.

Ionic indium(III) chloride hybrids incorporating a 2,2'-bipyrimidine ligand: studies on photoluminescence and structural transformation.

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.

Lithium Storage Performance Boosted via Delocalizing Charge in Zn Co PS /CoS of 2D/3D Heterostructure.

A promising anode material consisting of bimetallic thiophosphate Zn Co PS and CoS with 2D/3D heterostructure is designed and prepared by an effective chemical transformation. Density functional theory calculations illustrate that the Zn can effectively modulate the electrical ordering of Zn Co PS on the nanoscale: the reduced charge distribution emerging around the Zn ions can enhance the local built-in electric field, which will accelerate the ions migration rate by Coulomb forces and provide tempting opportunities for manipulating Li storage behavior. Moreover, the merits of the large planar size enable Zn Co PS to provide abundant anchoring sites for metallic CoS nanocubes, generating a 2D/3D heterostructure with a strong electric field.
