Insight into the construction of open-framework aluminophosphates

Area of Science:

• Materials Science
• Inorganic Chemistry
• Crystallography

Background:

• Open-framework aluminophosphates (AlPOs) are a significant class of materials.
• They possess neutral zeolitic and anionic frameworks with remarkable structural and compositional diversity.
• Their development over the past twenty-five years has led to complex architectures.

Purpose of the Study:

• To provide an insight into the construction of open-framework AlPOs.
• To reveal their general structural features and topological chemistry.
• To discuss the role of templating in the designed synthesis of AlPOs.

Main Methods:

• Literature review of AlPO synthesis and structural characterization.
• Analysis of topological chemistry principles in AlPO frameworks.
• Discussion of templating strategies in materials design.

Main Results:
