Selective synthesis of heteroleptic PdAB-cages: modulating size-preference of supramolecular hosts via endo-functionalization

The size complementarity between a host and a guest is a critical prerequisite for selective molecular recognition. Numerous artificial host systems have been designed to achieve size-selective recognition and chemical transformations. However, the inherent challenge lies in the fixed selectivity governed by a size-exclusion mechanism dictated by the host’s *** the selectivity necessitates structural modifications of hosts. Examples of host systems with modifiable sizeselectivity are rare. In this study, we present an approach to modulating guest-selectivity via endo-functionalization of supramolecular cavities. Heteroleptic Pd2A3B-cages are constructed with a Pd2A3precursor or directly from palladium ions and relevant ligands. Furthermore, the simultaneous and selective formation of multiple hetero-cages was achieved by simply mixing PdIIand the free ligands in a one-pot reaction. The fidelity of the assembly process relies on cooperative steric control at the periphery and within the cavity of the hetero-cages, respectively. The central steric group also functions as the endohedral moiety. Variations of the endohedral groups facilitate facile and modular derivatization of the microenvironment within the cages, enabling the fine-tuning of guest binding affinities as evidenced by titration experiments. This strategy offers a new solution for the development of customized host structures.

Narrowband photodetectors conventionally rely on optical structure design orbandpass filters to achieve the narrowband regime. Recently, a strategy forfilterless narrowband photoresponse based on the charge collection narrowing(CCN) mechanism was reported. However, the CCN strategy requires an electrically and optically “thick” photoactive layer, which poses challenges in controlling the narrowband photoresponse. Here we propose a novel strategy forconstructing narrowband photodetectors by leveraging the inherent ion migration in perovskites, which we term “band modulation narrowing” (BMN). Bymanipulating the ion migration with external stimuli such as illumination,temperature, and bias voltage, we can regulate in situ the energy-band structure of perovskite photodetectors (PPDs) and hence their spectral *** the Fermi energy levels obtained by the Kelvin probe force microscopy, the internal potential profiles from solar cell capacitance simulator simulation, and the anion accumulation revealed by the transient ion-drifttechnique, we discover two critical mechanisms behind our BMN strategy: theextension of an optically active but electronically dead region proximal to the top electrode and the down-bending energy bands near the electron transportlayer. Our findings offer a case for harnessing the often-annoying ionmigration for developing advanced narrowband PPDs.
