Abstract
- Two isostructural pillar-layer MOFs (JNU-105 and JNU-105-(NH<subscript>2</subscript>)<subscript>2</subscript>) have been successfully synthesized. JNU-105-(NH<subscript>2</subscript>)<subscript>2</subscript> exhibits a red-shifted luminescence "turn on" for formaldehyde without the interference from other VOCs and a detection limit of 1.87 ppb. In situ single-crystal transformation studies confirm the aminal formation on the pillar linker, which was attributed to the exclusive luminescence response toward formaldehyde.
