Synthesis and Anion Recognition of Triangular Prism Quinoline Cage with Reduced Symmetry

Abstract Organic molecular cages with low symmetry are promising to generate complex chemical environments for molecular recognition and catalysis. Herein, a new triangular prism cage with three rigid 8‐aminoquinoline‐2‐carboxylic acid derivatives as edges were synthesized. This molecular cage possesses reduced symmetry and contains both secondary amine and amide as hydrogen donating groups for molecular recognition. It could bind anions, such as NO 3 − , AcO − , and F − with moderate affinity.
