    　View Summary

    Molecular recognition of guest molecules within confined cavities enables effective modulation of their chemical and physical properties through noncovalent interactions. Because these modulated properties reflect the structural features of the host–guest assembly, the guest molecule can serve as a molecular probe to elucidate the origin of the host‐induced modulation. Herein, we report the formation of a host–guest complex composed of an emissive Ir(III) complex salt and a resorcin[4]arene host, along with the photophysical modulation of the guest via noncovalent interactions with the host. NMR spectroscopic analysis reveals a 1:1 binding stoichiometry, in contrast to the previously reported 6:1 stoichiometry, because the guest is larger than the cavity of the resorcin[4]arene hydrogen‐bonded hexameric capsule. This 1:1 binding mode is unambiguously confirmed by single‐crystal X‐ray diffraction analysis. The photoluminescent properties of the Ir(III) complex are enhanced in the presence of the host, indicating that electronic communication between the host and the guest plays a crucial role in modulating its photophysical behavior. These findings are further supported by density functional theory calculations. Overall, this article provides new insights into the photophysical dynamics of entrapped emitters and highlights the pivotal role of host–guest interactions in tuning emission properties.

    Abstract

    Supramolecular assemblies of a concaved aromatic host as an electron donor (D) and a cationic heterocyclic guest as an electron acceptor (A) are reported. These molecular units were noncovalently bound to afford charge‐transfer (CT) complexes in solution and a CT cocrystal, displaying drastic color change from colorless to orange. The binding motif of the assemblies in the solution state was analyzed by NMR spectroscopic analysis and visualized by X‐ray crystallographic analysis. Theoretical calculations for the assemblies revealed electronic communication between the D and A fragments, proving their CT characteristics. The CT complexes were stabilized by not only CT and cation‐π interactions, but also Coulomb interaction between the cationic acceptor unit and its anion supported by a hydrogen bond with a hydroxy group in the aromatic host, resulted in enhancement of orbital overlapping of the D‐A fragments. Owing to the strong D‐A interaction in the assemblies, the CT complexes undergo ultrafast charge recombination on a femtosecond timescale after photoexcitation of the CT transition, as confirmed by transient absorption spectroscopy. These results demonstrate that understanding of assembly motif and its noncovalent interactions can lead to create optical materials manipulating electron transition dynamics.
