Ferrocene molecule because it contains unique aroma and a transition metal element iron structure, having a special optical, electrical, magnetic properties, it has always been one of the hot research and technical applications, having in the preparation of a wide range of functional polymer materials Application prospects. Polyferrocene silane block copolymer is a new type of polymer containing ferrocene and organic silicon units in the main chain. With its controlled molecular weight and abundant self-assembly morphology, polyferrocene silane block copolymer continues to receive the attention of researchers. In this paper, poly (ferrocene) silane diblock copolymer was systematically introduced from three aspects: polymerization, self-assembly and application. Which focuses on the widely used anionic polymerization of anionic and further developed two-step polymerization, living polymerization mechanism is explained, different kinds of current summed successful synthesis of diblock copolymers; discussed in the selective solvent, Polydisferrocene silane diblock copolymer can be self-assembled to form cylindrical, tubular, spherical and other conventional micelles and sheets, brush and other complex micelles, the formation of micelles with the same activity as the polymerization characteristics, and in a certain stimulus Under the conditions of different types of micelles can complete the process of mutual transformation, in addition to the micelles can be partially functionalized to give its special properties; Finally, the poly-ferrocene silane diblock copolymer in drug delivery, nanomaterials , The specific examples of special catalysis, and prospects of its application.
