Abstract:
采用溶剂热的方法合成纯手性金属有机骨架[zn2(bdc)(l-lac)(dmf)]·(dmf)(zn-bld)化合物。研究合成温度、合成时间和合成液浓度对生成zn-bld晶体的产量和晶相结构的影响。结果表明:110℃为最佳合成温度;溶剂热合成12h,生成zn-bld晶体产量就已达到稳定与饱和;当合成温度为110℃,反应时间为12h,4种反应物的摩尔比为n(zn(no3)2·6h2o):n(h2bdc):n(l-h2lac):n(dmf)=6.0:1.5:1.5:387时,能够得到较高结晶度的纯相zn-bld晶体。优化条件下合成的zn-bld晶体对甲基苯基亚砜具有较高的对映体选择吸附性能,其对映体过量(e.e)值达到68.2%。通过热分析仪(tga)对zn-bld晶体的热稳定性进行了表征,在不高于400℃时,zn-bld晶体具有很好的热稳定性。
