Two organic-inorganic hybrid solids, namely, Zn(SCN)2(L-C9H11NO2)2 (1) and Zn4(SCN)4(L-C5H8NO3)4(H2O)4 (2), were synthesized by incorporating chiral amino acids into the zinc thiocyanate system. Compound 1 crystallizes as a monomeric complex in noncentrosymmetric space group P21, while compound 2 features circular tetrameric structure crystallized P21212. Both compounds exhibit phase-matching second-harmonic generation (SHG) responses, which are 1.4 3.1 times that of KH2PO4, respectively. Theoretical calculations conducted to determine source their SHG responses.

ConspectusThe invention of the laser marked a milestone in modern science and technology. Inorganic second-order nonlinear optical (NLO) crystals, with their unique frequency conversion capabilities, play critical role extending wavelength ranges. These materials are indispensable science, information transmission, other fields such as industrial Internet. As Moore's Law drives demand for shorter wavelengths higher-precision sources, development high-performance short-wave ultraviolet (UV) (<300 nm) NLO UV solid-state lasers has become increasingly important. While researchers have synthesized variety discovery largely relied on trial-and-error approaches, which not only time-consuming but also serendipitous rather than based rational design principles. Moreover, complexity designing these is compounded by need to meet several strict functional criteria, including short cutoff edge, strong second-harmonic generation (SHG) effect, moderate birefringence, all hinder efficient synthesis. The controlled synthesis therefore, remains significant scientific challenge.In this Account, we propose three-step strategy address challenge: (1) Rational screening highly polar groups, particularly new NLO-active groups novel bonding characteristics (π-localized distorted [O

We present two novel antimony(III)-based tellurite sulfate crystals, Sb2(TeO3)(SO4)2-P1̅ (I) and Sb2(TeO3)(SO4)2-P21/c (II), synthesized using a dual lone pair strategy that incorporates Sb3+ Te4+ ions into framework. This approach significantly enhances the birefringence of these compounds, with values 0.11 0.10 at 546 nm, respectively, surpassing those many previously reported mixed alkali metal/alkaline earth metal sulfates tellurites. Both compounds also exhibit excellent UV transparency cutoff edges 292 294 making them promising candidates for short-wave optical applications.

In the exploration of nonlinear optical (NLO) materials, developing new functional groups for high performance is essential. Achieving a balance among band gap, second harmonic generation (SHG), and birefringence within compound quite challenging. By directly connecting iodates borates by B-O-I bridges, two boroiodates with novel [B3IO8(OH)]3- [B4IO11]5- anionic groups, namely, Na[B3IO7(OH)] (NBIO-I) Na2[B4IO9](IO3) (NBIO-II), were successfully synthesized first time through boric acid melting method under different molar ratios H3BO3/NaIO3. NBIO-I (Pbca) features unique 1D ∞1[B3IO7(OH)]- chain composed corner-sharing [B3O6(OH)]4- [IO3]- hanging on both sides chain. contrast, NBIO-II (Cc) displays 2D layer ∞2[B4IO9]-, in which all are same side ∞2[B4O7]2- formed [B3O7]5- [BO3]3- groups. Remarkably, exhibits wide gap (4.3 eV), large (0.298@546 nm), strongest SHG response (7.8 × KDP) borate-iodates reported previously. This work not only discovered as promising NLO crystals but also provided an effective synthetic route excellent properties.
