Synthesis of Metallodendrimer based on Diphenylphosphine Functionalized Polyhedral Oligomeric Silsesquioxanes

초록

Nowadays, many researchers have focused on dnedrimers because of their potential utilities as catalysts, nano reactors, micelle mimics and so on. Dendrimers ,which has Polyhedral oligomeric silsesquioxane (POSS) as core, are synthesized. POSS dendrimers are synthesized by repetitive hydrosilylation and alkenylation reactions. These dendrimers are modified by diphenyl phosphine functional group ,which can act as metal ligand, at their periphery.. The second generation dendrimer has 32 diphenyl phosphine groups. Dendrimer reacts with various metal complexes to give metallodendrimer which can act as catalysts. Metallodendrimers are characterized by 1H, 13C, 29Si NMR and Mass spectral,
