copolymers (DHBCs) was synthesized and employed as additives in the crystallization of calcium tartrate tetrahydrate (CaT). We found that appropriate polymers can slow down the formation of the thermodynamically most stable racemic crystals as well as the formation of one of the pure enantiomeric crystals so that chiral separation by crystallization occurs even when racemic crystals can be formed. In addition
合成了一系列手性双亲水嵌段共聚物(DHBCs),并将其用作四水酒石酸钙(CaT)结晶的添加剂。我们发现合适的聚合物可以减缓热力学上最稳定的外消旋晶体的形成以及纯对映体晶体之一的形成,从而即使可以形成外消旋晶体也可以通过结晶发生手性分离。此外,DHBCs的存在会导致晶体形态的重大改变,从而产生复杂性更高的异常形态。我们的研究表明手性DHBC在整个结晶过程(特别是外消旋晶体系统)的手性控制中的潜在应用,
