Second-HarmonicGeneration in Organic–InorganicHybrid Cadmium Thiocyanates Containing Terminal Amino Acids
Using chiral amino acids as terminal ligands, colorless crystals of Cd<sub>3</sub>(SCN)<sub>6</sub>(l-C<sub>5</sub>H<sub>9</sub>NO<sub>3</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>·0.5CH<sub>3</sub>OH (<b>1</b>) and Cd(SCN)<sub>2</sub>(l-C<sub>6</sub>H<sub>14</sub>N<sub>4</sub>O<sub>2</sub>)<sub>2</sub> (<b>2</b>) were obtained by a solvent evaporation method. Compound <b>1</b> has a layered structure with a moderate second harmonic generation (SHG) efficiency (0.2 × KH<sub>2</sub>PO<sub>4</sub>) and a large birefringence (0.301 at 546 nm). Compound <b>2</b> features a molecular structure with a strong SHG efficiency (2.67 × KH<sub>2</sub>PO<sub>4</sub>) and a wide band gap (4.84 eV). Theoretical calculations were performed to elucidate the origin of the large SHG response of compound <b>2</b>.
