Doping-Induced Structure Variation of 1,3-Cyclohexane− Bis(methylamine)-Templated Zinc−Phosphorus Open Structures

By using 1,3-cyclohexane−bis(methylamine) (CHBMA) as the
template, a novel zinc phosphatophosphite (TJPU-3) with extra-large 20-ring channels was synthesized. Cobalt doping produced
a bimetallic phosphite (TJPU-6) with 12-ring apertures. While the
templates sit in the cis configuration in TJPU-3, they are in the
trans configuration in TJPU-6. This result has the potential for
separation and recognition of CHBMA isomers.

以1,3-环己烷-双(甲胺)(1,3-cyclohexane−bis(methylamine), CHBMA)为模板剂，成功合成了一种具有超大20元环孔道的新型亚磷酸磷酸锌(zinc phosphatophosphite)材料TJPU-3。通过钴掺杂策略，制备得到具有12元环孔口的双金属亚磷酸酯材料TJPU-6。研究发现，模板剂在TJPU-3中呈顺式构型(cis configuration)，而在TJPU-6中则为反式构型(trans configuration)。该研究成果在CHBMA异构体的分离与识别方向具有潜在应用价值。
