A Photoresponsive Smart Covalent Organic Framework [PDF]
Angewandte Chemie, 2015 AbstractOrdered π‐columnar structures found in covalent organic frameworks (COFs) render them attractive as smart materials. However, external‐stimuli‐responsive COFs have not been explored. Here we report the design and synthesis of a photoresponsive COF with anthracene units as the photoresponsive π‐building blocks.
