“…In previous studies, various H 2 bpz ligand, NO 3 – anion, and PF 6 – anion based materials exhibiting nonlinear optical properties have been reported, such as {[Cu(H 2 bpz)Br]·0.5H 2 O} n amounting for 1.0 × KDP, Rb 2 Na(NO 3 ) 3 corresponding to 5 × KDP, and [Zn(bipy)(ReC 6 H 4 HCN(O)C 6 H 3 NNC 6 H 4 CCRu(dppe) 2 Cl)]PF 6 equivalent to 0.4 × KDP (where R = CCC 6 H 4 OCH 3 , bipy = 2,2′-bipyridine) .

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.

“…[1][2][3]. Nonlinear optical effects arise upon the exposure of high intensity of lesser light to the optical material, and thus act as an influential part in the delocalization of π-electrons by light exposure [4,5]. There are double key aspects which regulate the NLO response of molecules such as (a) electron donor and acceptor π-electron conjugated arrangement as a connection providing the electronic link between them and, (b) the connection structure unit should be packed in a non-centrosymmetric way [6].…”

Crystal Structure, Topological and Hirshfeld Surface Analysis of a Zn(II) Zwitterionic Schiff Base Complex Exhibiting Nonlinear Optical (NLO) Properties Using Z-Scan Technique

A mononuclear Zn(II) complex of (Zn(H2L) (CH3OH) Cl2) (1) has been synthesized by using a nonlinear optically active Zwitterionic Schiff base which is 4-((2-hydroxy-3-methoxybenzylidene) amino) benzoic acid (H2L). Complex 1 has been structurally analyzed by FTIR and UV spectroscopy, TGA, Powder-XRD and single crystal X-ray diffraction. X-Ray crystallographic studies revealed Zn(II) complex crystallizes in a P21/c space group and exists in a distorted trigonal bipyramidal geometry (τ = 0.68). The topological analysis of complex 1 showed that the underlying net is characterized by an unknown topological type and point symbol {342.468.510}, and multilevel analysis of complex packing as dimer gives a 18-c uninodal net with unknown topological type and point symbol {348.499.56}. The calculation results of a Hirshfeld surface analysis have been investigated to explore the H-bonding within the crystal. Third-order non-linear properties were also studied, which revealed that the lower input power (5.0 mM) for the material shows full transparency; however, it becomes opaque for higher input power. Such limiting behavior of complex 1 suggests its potential for instrumental protective devices against high laser illuminations.

The heterobimetallic complexes [Cu(phen)(NC5H4HC=NC6H4C≡CC6H4C≡CRu(dppe)2Cl)]X (1 a‐4 a) and [Cu(bipy)(NC5H4H C=NC6H4C≡CC6H4C≡CRu(dppe)2Cl)]X (1 b‐4 b) (where X= I, ClO4, BF4, PF6; phen= 1, 10 phenanthroline, bipy= 2, 2′ bipyridine) have been prepared by the reaction of (NC5H4HC=NC6H4C≡CC6H4C≡CRu(dppe)2Cl) with copper salts in presence of phen or bipy as a coligand. Our synthetic attempts and successes are discussed in combination with spectroscopic and electronic characterization of the compounds. Comparison between phen and bipy complexes were studied by thermal and electrochemical analysis where, thermally robust complexes demonstrate quasireversible redox behaviour analogous to CuI/II/RuII/III couple. SEM of representative complexes 2 a and 2 b clarify the average size and morphology of the complexes. Room temperature luminescence influenced by varying coordinating ability of counter anions along with π‐acidic character in green‐yellow region was observed. Solvent dependant emission displays positive solvatochromism at ambient temperature. The second harmonic generation (SHG) efficiency of the complexes was measured by Kurtz‐powder technique indicating that all complexes display the second harmonic generation (SHG) property.
