Organic Nonlinear Optical Pyrrole-Based Hydrazone Materials |
| 초록 |
We report a new series of organic nonlinear optical crystals based on pyrrolic 4-nitrophenylhydrazone (NPH) derivatives with various substituents ( X: -H, -CH3, -CF3) on the hydrazone group (-CX=N-NH-) and their polymorphs. Among the NPH crystals, the monoclinic Pn phase of HNPH-Ⅰ and orthorhombic P212121 phase of HNPH-Ⅱ exhibit large second harmonic generation (SHG) efficiency of 420 and 210 times as that of reference urea, respectively, and yield large-size crystals. The microscopic and macroscopic nonlinearities in the crystallographic system were also investigated theoretically using quantum chemical calculations based on density functional theory (DFT). |
