Abstract Tuning phase transition temperature is one of the central issues in materials. Herein, we report a case study using enantiomer fraction engineering as promising strategy to tune Curie ( T C ) and related properties ferroelectrics. A series metal-halide perovskite ferroelectrics S −3AMP) x R 1−x PbBr 4 was synthesized where 3AMP 3-(aminomethyl)piperidine divalent cation varies between 0 1 (0 = enantiomers; 0.5 racemate). With change fraction, , second-harmonic generation intensity, degree circular polarization photoluminescence, photoluminescence intensity materials have been tuned. Particularly, when 0.70 − 1, continuously linear tuning achieved, showing tunable range about 73 K. This provides an effective means insights for regulating chiroptical functional

Organic-inorganic hybrid chiral small-molecule materials combine the inherent properties of both components; however, studies integrating chirality with rare-earth double-perovskite are limited. In this work, we synthesized two enantiomers three-dimensional (3D) double-perovskites, [R-3-HDMP]2CsEu(NO3)6 (1) and [S-3-HDMP]2CsEu(NO3)6 (2), by reacting R-3-HDMP S-3-HDMP (where 3-HDMP = 3-hydroxy-N,N-dimethylpyrrole) CsNO3 Eu(NO3)3 in a 2:1:1 ratio within an acidic solution. Both R-3-HDMPI S-3-HDMPI crystallize space group P212121 at room temperature, exhibiting transition from SHG-on to SHG-off (SHG second harmonic generation) upon heating cooling. The temperature-dependent X-ray single-crystal diffraction analysis carried out on compound 1 2, before after phase transition, disclosed transformation their groups noncentrosymmetric centrosymmetric. Additionally, incorporation elements as B-site cations imparts exceptional fluorescence compounds. These effectively merge unique characteristics molecules luminescence structures, paving way for innovative optical devices advanced information processing technologies.

Multifunctional coupled hybrid materials have extremely high potential for application in a variety of complex scenarios owing to advantages such as versatility and controllable properties. In this study, novel functional material with electromagnetic coupling properties [Ni(NCS)4(C6H13N4)2] (1) was obtained by naturally evaporating an aqueous solution nickel chloride hexahydrate, hexamethylenetetramine (HMTA), potassium thiocyanate raw materials. Structure–property characterization revealed that 1 crystallized the P21/n space group two-dimensional (2D) network structure formed hydrogen-bonding interactions between neighboring complexes. Calculations using Gaussian program indicated HMTA exhibited pronounced spatial molecular rotation. This induced obvious reversible dielectric cycling near 240 K, giving rise semiconducting optical band gap 3.35 eV.
