| SYNTHESIS |
The discovery that room-temperature ionic liquids can be used as solvents to prepare extended networks of coordination complexes could lead to another potentially useful application of these materials. Using a thermally stable and poorly coordinating ionic liquid as a solvent, chemistry professors Jing Li at Rutgers University and Scot Wherland at Washington State University and coworkers synthesized a crystalline copper-containing complex with a two-dimensional wavelike structure that resembles a brick wall [Chem. Commun., 2002, 2872]. Li and colleagues prepared the coordination complex—[Cu(I)(bpp)]BF4—by the reaction of Cu(NO3)2*3H2O with 1,3-bis(4-pyridyl)propane (bpp) using 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]) as solvent. Ionic liquids have a number of advantages over organic solvents, including high thermal stability, low volatility, and the ability to be tailored to meet specific synthetic needs, Li points out. The current work signifies the beginning of our efforts in exploring this area,” Li tells C&EN. Now, she explains, “We will conduct an extensive study to investigate the applicability of ionic liquids in the synthesis of coordination network structures in general.” |
