Nonlinear Optical Responses in One-Dimensional Zinc Thiocyanates Functionalized with Natural Amino Acids
Transparent crystals of Zn(SCN)<sub>2</sub>(l-C<sub>6</sub>H<sub>9</sub>N<sub>3</sub>O<sub>2</sub>) (<b>1</b>) and Zn(SCN)(l-C<sub>5</sub>H<sub>8</sub>NO<sub>2</sub>)(H<sub>2</sub>O) (<b>2</b>) were obtained using natural amino acids as linkers. The two compounds have one-dimensional structures that combine molecular and helical chiralities. They exhibit significant nonlinear optical responses that are phase matchable under 1064 nm laser irradiation. Notably, the second-harmonic generation efficiency of compound <b>2</b> (3.8 × KH<sub>2</sub>PO<sub>4</sub>) surpasses those of previously reported metal thiocyanates functionalized with natural amino acids.
