烷氧基化的杂金属功能化的聚氧乙烯醚是一个重要的策略，为定制这些多金属系统的物理和化学性质。本文报道了一系列异金属三烷氧基功能化簇合物[Ti 2 V4 O 5（OCH 3）11（OCH 2）3CR′]和[TiV 5 O 6（OCH 3）10（OCH 3）3CR′]的靶向合成。产品隔离揭示了设计标准的自组装的异金属POV-醇盐簇，并增加了进一步的多样性，这个家庭的聚氧乙烯醚。
Alkoxylation of heterometal-functionalized polyoxometalates is an important strategy for tailoring the physical and chemical properties of these multimetallic systems. Here, we describe the targeted synthesis of a series of heterometallic tris-alkoxy functionalized clusters [Ti2V4O5(OCH3)11(OCH2)3CR′], where R′ = CH3, C2H5, NO2, and [TiV5O6(OCH3)10(OCH3)3CR′], where R′ = C5H4N. Product isolation reveals design criteria for the self-assembly of heterometallic POV–alkoxide clusters, and adds further diversity to this family of polyoxometalates.
