The synthesis of aluminophosphate and germanosilicate LTA using a triquaternary structure directing agent

• Synthesis of a novel triquaternary organic structure directing agent with facile organic chemistry.
• Synthesis of aluminophosphate and silicoaluminophosphate LTA.
• Synthesis of germanosilicate LTA.
• Use of molecular modeling to compute the conformation of the organic in the microporous materials.

The use of triquaternary organic structure directing agents (OSDAs) for the synthesis of microporous materials is relatively unexplored. Here a triquaternary OSDA prepared by reacting 1,2-dimethylimidazole with 1,3,5-tris(bromomethyl)benzene promotes the formation of LTA in the aluminophosphate or germanosilicate reaction chemistries.
