Abstract Birefringent crystals have essential applications in optical communication areas. Low‐dimensional structures with inherited structural anisotropy are potential systems for investigating birefringent materials large birefringence. In this work, the zero‐dimensional (0D) [( p ‐C 5 H NO) 2 ZnCl ] ( 1 ) and [ 6 NO] [ZnCl 4 were obtained by introducing π‐conjugated NO (4HP) into three‐dimensional (3D) . Remarkably, exhibits a giant birefringence of 0.482@546 nm, which is largest among Zn‐based ultraviolet (UV) compounds 160 times that According to theoretical calculation analyses, polarizability, high spatial density, ideal distribution [(4HP) 0 cluster, low dimension result dramatically increased compared This work will provide valid route accelerating design synthesis excellent low‐dimensional systems.

The d0 transition metal oxides are the most commonly used nonlinear optical (NLO) materials in visible light region; however, their limited band gaps seriously hinder application ultraviolet (UV) and deep-ultraviolet (DUV) regions. Achieving double enhancement of gap birefringence by regulating anionic units helps to push phase-matching (PM) wavelength into UV/DUV Herein, starting from famous NLO material LiNbO3, a "dual-anion strategy" is proposed regulate [NbO6–xFx] octahedra, predicted Li2Nb2O6–xF2x·(LiF)y (x = 1, 2, 4; y 0, 2) exhibit dual-property magnification wide (3.82–6.26 eV, 1–3 eV larger than LiNbO3) extraordinary (0.100–0.322, 1–4 times that LiNbO3), along with strong second harmonic generation (SHG) response 2.6–6.2 × KDP. Remarkably, Li2NbOF5-I LiNbOF4-II have extremely short PM (λPM 209 nm) ever reported for oxyfluorides. Further analysis uncovers fluorinated modification edges increase octahedral anisotropy [NbO6−xFx] groups main reasons enhanced ability.

Borates provide an excellent platform for investigating the optical nonlinearity and linearity of crystals as photoelectric functional materials. In our work, borate derivatives with isolated [B3O3] six-membered rings structural features are preferred system due to their simple units properties. Herein, by utilizing target-oriented synthesis, a series derivatives, A2[B3O3F4(OH)] (A= NH4, Rb, Cs) (ABOFH), K2.3Cs0.7B3O3F6 (KCsBOF), Cs3[B3O3(OH)3]Cl3 (CsBOHCl), novel heteroanionic groups containing [BOxF4–x] (x = 0–3) and/or [BO2(OH)] were obtained. ABOFH, KCsBOF, CsBOHCl construct different two-dimensional pesudolayers featuring [B3O3F4(OH)], [B3O3F6], [B3O3(OH)3] units, respectively. Also, properties arrangement information these anionic studied. Among total five compounds, (NH4)2[B3O3F4(OH)] enlarged birefringence sufficient band gaps screened out promising birefringent optimally aligned configuration birefringence-active units. The successful results synthesis indicate more profound conclusion that now has diversified chemistry, effective strategy was proposed modify species optimize performance crystals.
