Crystalline structure of monohydrogentartrates, process for its preparation and application thereof |
摘要 |
The invention relates to new crystalline structures of left or right monohydrogentartrates exhibiting quadratic nonlinear effects and a wide transparency range extending from the visible to the near infrared, consisting of optionally substituted 2-amino-5-nitropyridinium cations used in combination with a polyanionic organic matrix made up of left or right monohydrogentartrate anions. It also relates to a process for the preparation of these crystalline structures, consisting in mixing one mole of the cation base with at least two moles of left and/or right tartaric acid. Finally, it relates to an electrooptical effect device comprising said crystalline structure. |
