二种活性八极分子的合成与表征

摘要

设计、合成了以均三嗪为核,苯乙烯基为桥、含活泼羟基的八极分子Ⅰ、Ⅱ,用IR、EA、1H MNR、UV-Vis等对其结构进行了表征,采用示差扫描量热法研究了八极分子的热性能.研究表明,在DMF中八极分子Ⅰ、Ⅱ的最大吸收波均为439 nm,热分解温度分别为401℃、475℃,具有较好的热稳定性,可用于制备性能优异的非线性光学材料.%Two octupolar molecules with thriazine as core,styryl conjugate as bridge and activity hydroxy group were designed and synthesized. The structures of two organic molecules were characterized by IR,elemental analysis, 1H MNR,UV-vis. Thermal properties were determined with DSC-TC. The maximum absorption wavelengths of the two compounds were both 439 run. Two compounds were thermally stable with the decomposition temperature of 401℃ and 475 ℃ respectively,and consequentlyit could be considered to be better choices for the preparation of NLO materials.
