Dynamic Near‐Infrared Circularly Polarized Luminescence Encoded by Transient Supramolecular Chiral Assemblies

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(32)

Опубликована: Май 13, 2024

Abstract Circularly polarized luminescence (CPL) is promising for applications in many fields. However, most systems involving CPL are within the visible range; near‐infrared (NIR) CPL‐active materials, especially those that exhibit high g lum values and can be controlled spatially temporally, rare. Herein, dynamic NIR‐CPL with a value of 2.5×10 −2 was achieved through supramolecular coassembly energy‐transfer strategies. The chiral assemblies formed by between adenosine triphosphate (ATP) pyrene derivative exhibited red signal ( 10 −3 ). further introduction sulfo‐cyanine5 resulted process, which not only led to NIR but also increased . Temporal control these realized introducing alkaline phosphatase fabricate biomimetic enzyme‐catalyzed network, allowing turned on. Based on enzyme‐regulated temporally controllable assemblies, multilevel information encryption system developed. This study provides pioneering example construction materials ability perform temporal via assembly strategy, expected aid design complex more closely resemble natural biological systems.

Herein, chiral deep eutectic solvents (DES) are prepared by lauric acid as hydrogen bond donors (HBD) and menthol acceptors (HBA). When achiral fluorescent molecules dopedin the menthol-based DES, they emit circularly polarized luminescence (CPL) with handedness controlled molecular chirality (l or d) of menthol. Remarkably, strategy is universal a series can be endowed CPL activity, showing full-color white upon appropriate mixing, which paves way to prepare materials. Interestingly, appears only in certain temperature range DES. Variable-temperature spectra other characterization methods reveal that H-bond network DES plays an important role inducing CPL.
