The encapsulation of coordination complexes in a tetragonal prismatic nanocage (1·(BArF)8) built from Zn-porphyrin and macrocyclic Pd-clip-based synthons is described. The functional duality of the guest ligand L1 allows for its encapsulation inside the cage 1·(BArF)8, along with the simultaneous coordination of ZnII, CuII, or FeIII metal ions. Remarkably, the coordination chemistry inside the host–guest adduct L1⊂1·(BArF)8 occurs in both solution solution and solid state. The resulting confined metallocomplexes have been characterized by means of UV-vis, ESI-HRMS, NMR, and EPR techniques. Furthermore, the emission of the Zn-porphyrin fluorophores of 1·(BArF)8 is strongly quenched by the encapsulation of paramagnetic complexes, representing a remarkable example of guest-dependent tuning of the host fluorescence.

自组装纳米笼中的锌，铜和铁配位配合物的设计
描述了在由锌卟啉和基于大环Pd-clip的合成子构建的四方棱柱形纳米笼（1·（BAr F）8）中配位络合物的包封。客体配体L 1的功能对偶性使其能够封装在笼子1 ·（BAr F）8内，同时具有Zn II，Cu II或Fe III金属离子的配位作用。值得注意的是，主-客体加合物内的配位化学大号1 ⊂ 1·（BAR ˚F）8在溶液溶液和固态下均会发生。所得的受限金属络合物已通过紫外可见，ESI-HRMS，NMR和EPR技术进行了表征。此外，1·（BAr F）8的Zn-卟啉荧光团的发射通过顺磁性配合物的包封而被强烈淬灭，代表了依赖于客体调节宿主荧光的显着实例。
