Опубликована: Янв. 24, 2024

Chiral CDots (c-CDots) not only inherit those merits from but also exhibit chiral effects in optical, electric, and bio-properties. Therefore, c-CDots have received significant interest a wide range of research communities including chemistry, physics, biology, device engineers. They already made decent progress terms synthesis, together with the exploration their optical properties applications. In this review, chiroptical chirality origin extinction circular dichroism (ECD) circularly polarized luminescence (CPL) is briefly discussed. Then, synthetic strategies summarized, one-pot post-functionalization ligands, assembly into architectures soft templates. Afterward, on applications are elaborated. Research domains such as drug delivery, bio- or chemical sensing, regulation enzyme-like catalysis, others covered. Finally, perspective challenges associated strategies, understanding chirality, potential provided. This review discusses latest developments helps toward better structure-property relationship along respective

Chiral Aggregation-Induced Emission Carbon Dot-Based Multicolor and Near-Infrared Circularly Polarized Delayed Fluorescence via a Light-Harvesting System

The Journal of Physical Chemistry Letters, Год журнала: 2024, Номер 15(7), С. 2049 - 2056

Опубликована: Фев. 13, 2024

Circularly polarized luminescence (CPL) materials are the research frontier of chiral luminescence. As a kind luminescent carbon material, dots (CDs) expected to become excellent candidates for construction CPL materials. However, CD-based circularly afterglow emission, especially multicolor and near-infrared remains great challenge due aggregation-caused quenching instability triplet excitons. In this work, we synthesized CDs with aggregation-induced emission using dithiosalicylic acid l/d-arginine as precursors through one-step solvothermal method. Notably, exhibit green delayed fluorescence (DF) in poly(vinyl alcohol) films. Furthermore, is successfully realized via engineering light-harvesting system which DF act energy donors fluorescent dyes colors ranging from yellow near infrared serve acceptors.
