Templated synthesis in polyoxometalate chemistry offers the advantages not only of improving production efficiency but also of accessing unknown structures as well. In this contribution, the template effect of the sulfate group unlocked an unprecedented polyoxovanadate-based metal–organic cluster (POV-MOC). More importantly, such a template effect is adjustable by means of several strategies, for instance, introduction of exogenous metal ions, regulation of mixed solvent systems, and bi-functionalization of organic linkers. Using such strategies, the structure of the POV-MOC matrix was able to be modified specifically on a local domain or completely remodelled into an unusual nanocapsule. Aside from the contribution to the structural evolution of as-made POV-MOCs, the tunable template effect could also be used to control of their adsorption properties, establishing a new route for the customization of function-oriented POV-MOCs.

通过可调模板效应控制多钒酸盐基金属有机团簇的结构和吸附特征

多金属氧酸盐化学中的模板合成不仅具有提高生产效率的优点，而且还具有获取未知结构的优点。在这项贡献中，硫酸盐基团的模板效应解锁了前所未有的基于多钒酸盐的金属有机簇（POV-MOC）。更重要的是，这种模板效应可以通过多种策略来调节，例如引入外源金属离子、混合溶剂体系的调节以及有机连接体的双功能化。使用这种策略，POV-MOC 基质的结构能够在局部域上进行特定的修改或完全重塑为不寻常的纳米胶囊。除了对现有POV-MOCs的结构演化做出贡献外，可调模板效应还可以用于控制其吸附性能，为功能导向的POV-MOCs的定制建立新途径。
