Metallostars: High-Nuclearity Linearly Developed Nanostructures Containing Multiple Cluster Motifs
摘要:
Metallostars are complexes in which a single branching site bears a number of metallated arms. Although they are related to metallodendrimers, they have the advantage of being capable of extending in an unlimited sense; in contrast to metallodendrimers, steric interactions decrease with increasing generation number. In this paper a series of polyalkyne stars with four and six arms, based upon a single tetrahedral carbon core and a benzene core, respectively, are reported and their reactions with [Co-2(CO)(8)] to give metallostars that contain multiple {C2Co2(CO)(6)} motifs are described.
