Molecular engineering of microporous crystals: (VII) The molar ratio dependence of the structure-directing ability of piperazine in the crystallization of four aluminophosphates with open-frameworks

- Four aluminophosphates were synthesized in the presence of piperazine.
- The crystallization processes of three aluminophosphates were investigated.
- A species that may promote the formation of microporous AlPO-CJB2 was identified.
- The factors affecting the structure-directing ability of piperazine were studied.
