Soft-Landing Isolation of Multidecker V_2(benzene)_3 Complexes in an Organic Monolayer Matrix: An Infrared Spectroscopy and Thermal Desorption Study

摘要

Gas-phase synthesized metal-benzene sandwich complexes have generated a great deal of attention because of their unique metal-and size-dependent characteristics, originating from their one-dimensional (1-D) anisotropic structures. In particular, the complexes consisting of vanadium (V) and benzene, V_n(ben-zene)_(n+1), efficiently form multidecker sandwich structures. To this point, a number of experimental and theoretical studies have been devoted to the characterization of their geometric, electronic, and magnetic properties. Their 1-D sandwich structure, for instance, ensures that such V_n(benzene)_(n+1) clusters possess a quasi-band electronic structure, and their magnetic moments increase monotonically with the cluster size. Thus, this type of cluster is one of the most attractive candidates for molecular-scale building blocks in future spin-electronic devices.
