Formation and Fine-tuning of Metal-Organic Frameworks with Carboxylic Pincers for the Recognition of a C₂H₂ Tetramer and Highly Selective Separation of C₂H₂/C₂H₄

Highly efficient ethylene (C 2 H 4 ) and acetylene (C 2 H 2 ) separation is a great challenge and an important process in current industry. Herein, we finely tune a new family of 6-c metal-organic frameworks...
