Luminescent hydrogels with flexibility and biocompatibility have attracted considerable interest in anti-counterfeiting application. However, conventional luminous substance is prone to release into the surrounding environment, causing accumulation biotoxicity. The green synthesis of repeatable fluorescent materials from biomass remains challenging. Herein, we report assembly nano-cellulose hydrogel doped naturally originated multiple active sited carbon dots (CDs) demonstrate sustainable usage information encryption. problem CDs leaching matrix was solved via strong chemical interactions between cellulose nanofibers. facilely prepared showed extraordinary mechanical properties fatigue resistance (i.e., stress, compressive modulus, toughness were up 1607.30 kPa, 368.33 191.54 kJ/m3, respectively). Furthermore, this cellulose-based gel displayed bright fluorescence under UV light, which could be quenched by Fe3+ ions recovered an ascorbic acid/EDTA-2Na mixture solution. Therefore, coded can easily input interpreted ionoprinting technique, realizing a simple display erasing procedure.

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, Journal Year: 2024, Volume and Issue: 15(7), P. 2049 - 2056

Published: Feb. 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.

Carbon Dot Synthesis and Purification: Trends, Challenges and Recommendations

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(48)

Published: Aug. 20, 2024

Abstract Carbon dots (CDs) have rapidly emerged as a new family of carbon‐based nanomaterials since their initial discovery two decades ago. Numerous appealing properties, such precursor and synthesis process flexibility, tunable photoluminescence, good biocompatibility, enabled widespread applications in sensing, catalysis, energy, biomedical fields. As the field expands, notable efforts recently focused on mechanistically elucidating structural formation optical behavior CDs. However, absence “clean” CDs presents major obstacle to achieving solid understanding these aspects. Often, claimed are, fact, mixture small molecules, oligomers, nano‐sized aggregates, or even microparticles. Such coexistence impurities markedly impacts physicochemical properties resulting CD‐based mixtures, hampering resolution key mechanistic questions. Here, we aim address this fundamental shortcoming field, going beyond customary focus existing reviews that predominantly cover synthesis, performance, application prospects. We begin with an overview CD then thoroughly examine purification methods, including filtration, dialysis, electrophoresis, chromatography. The insights provided here will guide researchers towards obtaining high‐quality CDs, employing proper combinations available tools, ultimately paving way for more demanding applications.
