A series of new acentric fluoroborophosphates, namely, RbBPO4F, CsBPO4F and (NH4)2BPO4F2, have been obtained by combining BO3F or BO2F2 with a PO4 tetrahedron. The structures of the isomeric RbBPO4F and CsBPO4F feature a three-dimensional diamond framework, in which a BO3F (or PO4) tetrahedron corner is shared with three PO4 (or BO3F) tetrahedra, forming 1D tunnels of eight-membered rings (MRs) along the three axial directions, which are filled with alkali cations. (NH4)2BPO4F2 exhibits a 3D supramolecular structure, in which 1D [BPO4F2]−∞ anionic chains along the a axes based on corner-sharing and alternating PO4 and BO2F2 tetrahedra are further interconnected with ammonium cations by electrostatic attractions and hydrogen bonds. RbBPO4F, CsBPO4F and (NH4)2BPO4F2 display second-harmonic generation (SHG) signals approximately 0.4, 0.6 and 0.8 times that of KH2PO4 (KDP) and exhibit short UV absorption edges (<200 nm). Measurements of thermal stability and optical properties and theoretical calculations have also been performed.

Two new Schiff-base modified vanadium complexes, [VIVO(C7 H5O)2(N2C6H10)] (1) and [VVO2(C7H5O)(N2C6H12)] (2), were synthesized under hydrothermal conditions, in which salicylaldehyde and cyclohexanediamine were used directly to form Schiff-base ligands during the reactions. The structures of 1 and 2 were characterized by EA, FT-IR, UV-vis, SCXRD and PXRD, EPR spectroscopy and magnetic susceptibility measurement. Due to the good optical activity of Schiff-base ligands and the existence of conjugated benzene rings in 1 and 2, the delocalized electronic effects between Schiff-base ligands and vanadium can be improved. Therefore, the third-order non-linear optical (NLO) properties of these complexes were investigated. The results of the open aperture Z-scan tests show that the two-photon absorption (TPA) cross-sections (σ) of the complexes are 1033 and 1041GM, respectively, which indicated that they both have potential applications as NLO materials.

Metal oxyhalides have attracted extensive attention as fascinating nonlinear optical (NLO) materials. Here, two barium niobium oxyfluorides, Ba3Nb2O2F12(H2O)2 (1) and Ba0.5NbO2F2(H2O) (2), have been obtained by regulating the O/F ratio in Nb–O–F units (NbOF6 pyramids to NbO4F2 octahedra). The overall NLO effect is improved from 1 to 2 with larger second-harmonic generation (SHG) intensities (0.9 to 1.7 × KH2PO4 (KDP)) and maintainable large band gaps (>3.0 eV) by regulating the O/F ratio in Nb–O–F units (1:6 to 4:2).

Guanidine units have garnered significant attention in the study of ultraviolet (UV) nonlinear optical (NLO) materials due to their excellent microscopic optical properties, making them ideal systems for developing novel optical devices. A novel guanidinium-templated UV NLO crystal, [C(NH2)3]SbCl4 (GSC), was successfully synthesized via an aqueous solution method. GSC crystallizes in the orthorhombic chiral space group P212121, featuring a seesaw shaped [SbCl4]− anion. Remarkably, GSC exhibits a moderate second harmonic generation (SHG) response of 1.1 × KDP at 1064 nm and a large refractive index difference of 0.2 at 546 nm. This NLO effect originates from the synergistic interaction between the [C(NH2)3]+ unit and the stereochemically active [SbCl4]− unit. This work provides a candidate for the guanidine family of NLO materials.

1-(4-methoxyphenyl)-3-(3,4-dimethoxyphenyl)-2-propen-1-one(DMMC), a chalcone derivative was synthesized by Claisen-Schmidt condensation reaction method. The growth of DMMC in methanol was used the slow evaporation technique. Single crystal X-ray diffraction revealed that the space group of DMMC is P2 1 . The intermolecular interaction of crystal was analyzed by Hirshfeld surface. The second harmonic generation efficiency of DMMC was measured by Kurtz-Perry powder method. When the particle size was between 250 and 300 μm, the SHG efficiency of DMMC was the largest, which was about 60 times that of the KDP with the same particle size. All functional groups of the crystal were identified by FT-IR and 1 H NMR spectral. This crystal had a wide transmission range in the region of 350−2000 nm with the cut off wavelength is 400 nm. The thermal properties of the sample were tested, and the melting point was at 95.59 °C. The dielectric constant of the compounds was found to be 17 below 45 °C.

A series of acrylate group terminated fluorinated polycarbonates containing 4,4-cyclohexylidenebis phenol (BPZ) (AF-Z-PC MAs) or dodecyl chains (AF-Ali-PC MAs) were synthesized. These polymers were further doped with chromophores and crosslinked under a UV lamp. With these doped polymers as the functional layer, we successfully obtained straight and Y structure waveguides by a direct writing method for electro-optical modulator devices. These cross-linked polymers displayed good thermal stability, low optical loss and a high refractive index. In addition, after polarization, the electrooptic coefficients r33 of the doped films were 10 pm V−1 and 9 pm V−1, measured by the Teng–Man method, respectively. The results showed that the direct writing method was a simple and effective way to fabricate Mach–Zehnder structure waveguides and these new macroacrylate terminated polycarbonates had great potential in the application of electro-optical modulator devices.

A novel organic-inorganic hybrid crystal, (C 5 H 12 NO)H 2 PO 4 (4-(Hpd)H 2 PO 4 ), has been synthesized by evaporation method under ambient atmosphere. Based on structure analysis, the compound crystalizes in the polar space group P2 1 with the parameters a = 8.6074 (6) Å, b = 6.3134 (4) Å and c = 9.0934 (7) Å. By the hydrogen bonds , 4-(Hpd) + cation and (H 2 PO 4 ) - anion were aligned to form an alternatively intercalated three-dimensional framework. Physical properties including thermal performance, linear and nonlinear optical characteristics were identified. On the basis of the results, a high and broad transmittance has been exhibited at the ultraviolet region and the optical band gaps is proved about 3.71 eV for 4-(Hpd)H 2 PO 4 crystal. PL presented an obvious emission peak with the position at 450 nm. SHG response has been demonstrated and the intensity is about 0.15 time that of KDP. In particular, First-principle density functional theory (DFT) calculation was performed to get insight into the correlations between optical properties and electronic structure. The results reveal that the interactions of 4-(Hpd) + cations and (H 2 PO 4 ) - anions are associated with the high transmittance and SHG.

The key to achieving nonlinear optical (NLO) crystals with superior optical properties lies in the development of new high-performance functional units and their precise arrangement. In this study, we identify the polar covalent tetrahedron (PO3NH3)−, with its remarkable optical properties, as a novel deep-ultraviolet (DUV) NLO-active unit for the first time. To ensure the (PO3NH3)− units are accurately aligned, we selected NaNH4PO3F·H2O as a template. Subsequently, we successfully synthesized NaPO3NH3, wherein the (PO3NH3)− units were arranged in an orderly manner. This excellent ordered arrangement of (PO3NH3)− units enables NaPO3NH3 to exhibit not only a significant SHG effect (1.2 × KDP), but also the largest birefringence (0.062@546.1 nm) among DUV non-π-conjugated phosphate systems.

Developing new short-wavelength nonlinear optical (NLO) crystals has always been a significant and challenging area of research. Herein, guided by the cooperative optimization strategy, three new rare-earth metal borate fluorides, K 2 GdB 3 O 6 F 2 , Rb 2 LuB 3 O 6 F 2 , and Cs 2 LuB 3 O 6 F 2 , are rationally designed and fabricated by synergically assembling advantageous functional groups. Among them, a structural evolution from centrosymmetric K 2 GdB 3 O 6 F 2 to non-centrosymmetric Rb 2 LuB 3 O 6 F 2 and Cs 2 LuB 3 O 6 F 2 reveals that the [B 3 O 6 ] group contributes to the control of structural symmetry, owing to its sensitivity to the coordination of rare earth metal polyhedra. Notably, all the three title compounds exhibit short cutoff edges less than 200 nm, with Cs 2 LuB 3 O 6 F 2 displaying a large experimental frequency doubling effect of 1.5 × KH 2 PO 4 . The type-I shortest phase-matching wavelengths for Rb 2 LuB 3 O 6 F 2 and Cs 2 LuB 3 O 6 F 2 are evaluated to be 210 and 202 nm, respectively, indicating their potential for direct output of 213 coherent lights through a fifth harmonic generation process of Nd: YAG laser. This study provides new insights into the rational design and development of short-wavelength NLO materials by exploring the sensitivity of the [B 3 O 6 ] groups to the surrounding coordination environment, thereby fostering innovation in the field of NLO materials.

A long-lasting challenge in ultraviolet (UV) nonlinear optical (NLO) materials design is to combine conflicting and harsh properties into one structure, including wide UV transparency, strong NLO efficiency, and moderate birefringence to realize phase-matching at short wavelength. A fluorine-directed material design strategy is adopted to accelerate the process of finding NLO materials with optimal performances. In this work, taking LiB 3 O 5 (LBO) as a maternal structure, one O atom with two F atoms is substituted and LiNaB 6 O 9 F 2 which possesses novel double interpenetrating 3 [B 6 O 9 F 2 ] ∞ networks and fluorine-directed optimal performances including enhanced birefringence and phase-matching capacity is successfully obtained. The perfect balance among deep-UV cutoff edge, large second-harmonic generation (SHG) response (1.1 × KDP), and moderate birefringence (0.067 at 1064 nm) of LiNaB 6 O 9 F 2 makes it a promising UV NLO crystal.
