水热/溶剂热法合成单晶时,加的一点点硝酸的作用是什么?有的文献报道,在合成单晶时,用羧酸做配体,水热或溶剂热的方法合成,有时候要加那么一点点硝酸,不知道这样做的目的是什么?如下边的:To prepare crystals of JOU-34, a mixture of Zn(NO3)2⋅6H2O (0.045 mmol, 13.12 mg), H4TBAPy (0.015 mmol, 10.27 mg), DMF (2.5 mL), and HNO3 (60 μL, 65 wt%) were ultrasonic treated for 5 min, transferred into a 10 mL pressure-resistant glass bottle, and then heated at 120 ◦C for 72 h. Yellow block crystals were isolated by filtrating, washing with fresh DMF, and drying under air. H4TBAPy= 1,3,6,8-tetrakis (p-benzoic acid) pyrene查看更多1个回答 . 19人已关注
