| titleOfInvention | Composite quaternary ammonium salt nonlinear optical crystalline material and preparation method thereof |
| abstract | The invention belongs to the technical field of fine chemical synthesis, and particularly relates to a composite quaternary ammonium salt nonlinear optical crystalline material which is picrate anion and 1-benzyl-4-dimethylThe chemical structure of the compound composed of the amino pyridine quaternary ammonium salt cations is shown as the formula (I), and is abbreviated as [ BzDMAP][PIC]. The preparation method comprises the following steps: the preparation method comprises the steps of preparing 1-benzyl-4-dimethylamino pyridinium, preparing silver picrate and preparing compound quaternary ammonium salt. The composite quaternary ammonium salt crystalline material has more excellent nonlinear optical activity, and the first hyperpolarizability of the material is 86.58 multiplied by 10 ‑31 esu, about 12.64 times that of the reference crystal KDP, is significantly higher than the picric acid salt anion and quaternary ammonium salt cation, especially in the presence of electrostatic interactions and a large number of C-H.O hydrogen bonding interactions between the anion and cation, and plays an important role in the generation and stability of the crystal structure, as well as in the enhancement of the optical properties. |
