Hypervalent iodine(III) have widely been utilized for organic synthetic reagents. They are also recognized as positive charge‐assisted, exceptionally robust biaxial halogen bond donors, while their potential in supramolecular materials is barely explored. This work reports a cyclic diaryliodonium ion as biaxial halogen bonding donor that displays remarkable binding affinity toward phenanthroline or acridine acceptors with chiral pendants. Biaxial halogen bonding enables chiroptical evolution in solution, allowing for rational control over supramolecular chirality. Leveraging their strong binding affinity, the halogen bonding complexes manifested amorphous properties and deep eutectic behavior in the solid state. Capitalizing on these attributes, this work achieves the successful preparation of supramolecular glasses and deep eutectic solvents. Additionally, halogen bonding appended light irradiation‐triggered luminescence through a hydrogen atom transfer process, showing applications in anti‐counterfeit and display.

Amino acid‐based biomolecular glasses represent an emerging material to meet the demand for sustainable development. However, most amino acids are difficult to vitrify due to their strong crystallization tendency, limiting further advancements of this field. In this study, we demonstrate that the introduction of counterions effectively suppresses crystallization, as hydrogen bonds within the system stabilize the disordered structures. Based on this, we propose a counterion co‐assembly strategy to synthesize a wide range of amino acid‐based glasses. This strategy enables the facile fabrication of glass with customizable shapes, high mechanical rigidity, and tunable multicolor fluorescence, ranging from blue to red depending on the excitation wavelength. Furthermore, this strategy allows the integration and enhancement of counterion properties within the glass matrix. Through the co‐assembly of phosphorescent counterions, we synthesized a series of long‐persistent luminescent glasses with significantly extended afterglow lifetimes. This work presents an effective approach for the synthesis of amino acid‐based glasses and provides insights into the development of supramolecular glasses with tailored functionalities.
