Anion-Tuned Synthesis of Ag Coordination Compounds: Approaches for Optimizing Second-Harmonic-Generation (SHG) Response

Abstract

With the rapid development of information technology, the demand for optoelectronic functional materials is increasing. Nonlinear optical materials are needed as basic materials in the optoelectronic industry, such as optical switches, optical communication, optical information processing, optical computers, laser technology, and so on. Therefore, nonlinear optical materials have received extensive attention in recent decades, but for nonlinear optical materials, the difficulty in their synthesis is the synthesis of noncentrosymmetric crystal structures. In this paper, three new compounds, namely Ag 2 (H 2 bpz) 2.5 (PF 6 )(OH)•H 2 O (1), Ag 2 (H 2 bpz) 2.5 (SbF 6 )(OH)•H 2 O (2), and Ag(H 2 bpz)(NO 3 )•H 2 O (3), have been synthesized and characterized by X-ray singlecrystal diffractometry; compounds 1 and 2 crystallize in a noncentrosymmetric space group. It is worth noting that the characterization results show that, through a simple hydrothermal reaction, we have successfully verified the feasibility of the theory of synthesizing noncentrosymmetric structures. In addition, compounds 1 and 2 synthesized by our simple method show second-harmonic generation, and it is phasematchable.

Synthesis, X-ray structures, and magnetic properties of seven polynuclear Cu(ii) complexes containing pyrazole-3,5-dicarboxylate with various ancillary ligands

“…The structural self-assembly is governed by many factors such as metal ions, ligands, reaction temperature, counterions, solvents, and pH of the reaction. [7][8][9][10][11][12] The parameters that are most important for the magnetic property are the bridging ligand and the paramagnetic metal center. Changes in the type of metal center and bridging ligand result in the creation of materials with varying magnetic properties.…”
