Anion Dependent Self-Assembly of Polynuclear Cd-Ln Schiff Base Nanoclusters: NIR Luminescent Sensing of Nitro Explosives
Two types of polynuclear Cd-Ln complexes [CdLnL(NO )Cl (DMF) ] [Ln = La ( ) and Nd ( )] and [Ln CdL (NO ) (DMF) ](OH) [Ln = La ( ) and Nd ( )] were constructed using a new Schiff base ligand which has a long backbone with two phenyl groups. The Schiff base ligands show a "twist" configurat...
