Near-infrared-emissive metal–organic frameworks

Emerging as a promising novel material, near-infrared-emissive metal-organic frameworks (NIR-emissive MOFs) have drawn much attention for their unique properties. Here, we demonstrate recent advancements in enhancing the NIR emission performance of MOFs as well as their appealing applications in bio-imaging, sensing and barcoding. The present challenges are briefly concluded and the possible future prospects are discussed.
