Neodymium(III) organic frameworks (Nd-MOF) as near infrared fluorescent probe for highly selectively sensing of Cu2Â +

A novel Nd-MOF {[Nd2(NH2-BDC)3(DMF)4]}n (1) based on Nd(III) dinuclear nodes is synthesized and structurally characterized. 1 displays the octahedral networks linked by infinite connection of the cube units, in each cube unit the dinuclear nodes are used as the vertexes. Near infrared luminescent measurements indicate that 1 can detect Cu2 + with high sensitivity and selectivity, it represents the first near infrared fluorescent probe of MOFs used in detection.158
