Solvent-dependent luminescence behavior of a new charge-transfer Cu(I)-MOF: An experimental and theoretical investigation

• A new charge-transfer Cu-MOF has been synthesized and characterized.
• Complex 1 has a good thermal stability.
• Complex 1 exhibits intriguing solvent-dependent luminescence behaviors.
• The luminescent origin of 1 is confirmed via the in-depth computations.

Herein we report the first charge-transfer metal–organic framework with open Cu(I)-sites, which exhibits intriguing solvent-dependent luminescence behaviors. An extended analysis of experimental and computational result indicates that strong metal–solvent bonding interaction plays a dominant role in the sensing of various solvents.
