Phosphonate and sulfonate metal organic frameworks
Recent progress in phosphonate and sulfonate MOFs is reviewed with an emphasis on open frameworks. These two ligating functionalities are paired due to their structural analogy but the review will show that their differences likely outweigh their similarities when it comes to their framework structures and properties. Examples that are highlighted focus on new routes to open structures, demonstrations of porosity and functionality, and examples with dynamic structures. This critical review is geared to researchers interested in designing open framework solids (134 references).
