Phase-Matching Second-Harmonic Generation in Zero-Dimensional Zinc Thiocyanates Ligated with Chiral Amino Acids
Two organic-inorganic hybrid solids, namely, Zn(SCN)<sub>2</sub>(L-C<sub>9</sub>H<sub>11</sub>NO<sub>2</sub>)<sub>2</sub> (<b>1</b>) and Zn<sub>4</sub>(SCN)<sub>4</sub>(L-C<sub>5</sub>H<sub>8</sub>NO<sub>3</sub>)<sub>4</sub>(H<sub>2</sub>O)<sub>4</sub> (<b>2</b>), were synthesized by incorporating chiral amino acids into the zinc thiocyanate system. Compound <b>1</b> crystallizes as a monomeric complex in the noncentrosymmetric space group <i>P</i>2<sub>1</sub>, while compound <b>2</b> features a circular tetrameric structure crystallized in the noncentrosymmetric space group <i>P</i>2<sub>1</sub>2<sub>1</sub>2. Both compounds exhibit phase-matching second-harmonic generation (SHG) responses, which are 1.4 and 3.1 times that of KH<sub>2</sub>PO<sub>4</sub>, respectively. Theoretical calculations were conducted to determine the source of their SHG responses.
