N2 - The synthesis and properties of discrete nanometer scale materials is of critical importance for the development of advanced nanoscale materials. Here we report the solid structural characterization and solution photophysical properties of self-assembled [Cu2(OC12-bdc)2 L2]12 [(OC12-bdc)2- = 5-(dodecyloxy)-1,3-benzenedicarboxylate; L = solvent] nanoballs (hereafter OC12-nanoball or OC12-NB). The crystal packing reveals that selected OC12 moieties thread through the windows of adjacent OC12-NB molecules and thereby sustain a 1-fold diamondoid network. Unlike other NBs the OC12-NBs are readily soluble in a variety of hydrocarbon solvents including benzene, toluene, and hexane. The solution properties of the OC12-NB were examined in toluene using optical absorption, and both steady-state and time-resolved fluorescence methods. These results indicate that the electronic properties of the OC12-NB are similar to those of the OH-nanoball previously examined (Larsenet al.Inorg. Chem. 2007, 46 (5), 5904 -5910). In addition, fluorescence polarization results further indicate that the OC12-NBs remain intact in both toluene and hexane solutions. Overall, these data suggest a general stability for Cu(II) NBs containing a variety of substituted isophthalic acid ligands in solution.
