Thiacalix[4]arenes as a family of promising ligands have been widely used to construct polynuclear metal clusters, but scarcely employed in silver nanoclusters. Herein, an anion-templated Ag88 nanocluster (SD/Ag88a) built from p-tert-butylthiacalix[4]arene (H4TC4A) is reported. Single-crystal X-ray diffraction reveals that C4-symmetric SD/Ag88a resembles a metal-organic super calix comprised of eight TC4A4- as walls and 88 silver atoms as base, which can be deconstructed to eight [CrO4@Ag11(TC4A)(EtS)4(OAc)] secondary building units arranged in an annulus encircling a CrO42- in the center. Local and global anion template effects from chromates are individually manifested in SD/Ag88a. The solution stability and hierarchical assembly mechanism of SD/Ag88a are studied by using electrospray mass spectrometry. The Ag88 nanocluster represents the highest nuclearity metal cluster capped by TC4A4-. This work not only exemplify the specific macrocyclic effects of TC4A4- in the construction of silver nanocluster but also realize the shape heredity of TC4A4- to overall silver super calix.

分层组装的88核银-硫杂杯[4]芳烃纳米簇。
硫杂杯[4]芳烃作为一个有前途的配体家族已被广泛用于构建多核金属簇，但很少用于银纳米簇中。在此，报道了由对叔丁基硫杂杯[4]芳烃（H4TC4A）构建的阴离子模板Ag88纳米簇（SD / Ag88a）。X射线单晶衍射表明，C4对称SD / Ag88a类似于金属有机杯，由八个TC4A4-作为壁和88个银原子作为碱，可以分解为八个[CrO4 @ Ag11（TC4A）（ （EtS）4（OAc）]次级建筑单元，布置在环形空间内，中间环绕CrO42-。铬酸盐的局部和整体阴离子模板效应分别在SD / Ag88a中显示。通过电喷雾质谱研究了SD / Ag88a的溶液稳定性和分层组装机理。Ag88纳米簇代表了由TC4A4-覆盖的最高核金属簇。这项工作不仅例证了TC4A4-在银纳米团簇的构建中的特定大环效应，而且还实现了TC4A4-对整个银超级杯的形状遗传。
