A Cuprous/Lanthanide-Organic Framework as the Luminescent Sensor of Hypochlorite.

A new 3D framework {[Eu2 Cu(IN)5 (CO3 )(H2 O)] ⋅3 H2 O}n  (1) was obtained and structurally characterized, containing CuI and an unusual lanthanide duplex chain. The luminescent explorations of compound 1 suggest that 1 could emit the characteristic emission of CuI , and 1 can act as the luminescent sensor of ClO- with the detection limit of 10-5  m. Notably, 1 represents the first example of MOF-based sensor for detecting ClO- .
