Abstract

Abstract : Telechelic amphiphilic metallopolymers can self-assemble in solution to create nanosized flowerlike vesicles, where the two platinum(ii ) complex ends are connected to the same vesicular core and the central PEG chains form loops as a corona. Abstract : Here we have designed and synthesized a series of platinum(ii ) complex end-difunctionalized poly(ethylene glycol)s (PEGs). For the first time, these telechelic amphiphilic metallopolymers can self-assemble in solution to create nanosized flowerlike vesicles, where the two platinum(ii ) complex ends are connected to the same vesicular core and the central PEG chains form loops as a corona. Such a self-assembly process correlates well with spectroscopic changes and luminescence enhancements that originate from Pt⋯Pt and π–π stacking interactions. Moreover, thermal annealing of the nanosized flowers leads to a morphological transformation to micrometer size, giant flowerlike vesicles. The present work, combining telechelic polymers with metal complexes, will open up a new approach for the design of functional metallopolymers with controllable self-assembly.
