The synthesis of highly ordered chiral periodic mesoporous organosilica (PMO) materials is described using a novel approach. Chiral dopants featuring removable chirality were combined with freely rotating bulk monomers, resulting in a bulk chiral material with handedness related to the chiral dopant. Once incorporated into the PMO, removal of the chiral-linker in the dopant is readily accomplished
使用一种新颖的方法描述了高度有序的手性周期性介孔有机二氧化硅(PMO)材料的合成。将具有可去除手性的手性掺杂剂与自由旋转的本体单体结合,得到具有与手性掺杂剂相关的手性的本体手性材料。一旦掺入到PMO中,就很容易完成掺杂剂中手性连接基的去除,并且在PMO材料中完全保留了圆二色性信号的情况下发生,而在前体分子中,这种转化将导致手性的完全丧失。即使在长时间的水热处理后,PMO材料的手性仍然保留,这表明在固体PMO壁内可以稳定地诱导手性。
