摘要: We herein report the divergent and convergent synthesis of coordination star polymers (CSP) by using metal–organic polyhedrons (MOPs) as a multifunctional core. For route, copper-based great rhombicuboctahedral MOPs decorated with dithiobenzoate or trithioester chain transfer groups at periphery were designed. Subsequent reversible addition–fragmentation (RAFT) polymerization monomers mediated gave polymers, in which 24 polymeric arms grafted from MOP On other hand, route provided identical CSP architectures simple mixing macroligand copper ions. Isophthalic acid-terminated (so-called macroligands) immediately formed corresponding CSPs through reaction copper(II) This enabled us to obtain miktoarm tunable compositions ligand alone. powerful method allows instant access wide variety multicomponent polymers...
