Water is a typical impurity in organic solvents, so it significant to determine its presence quantitatively and qualitatively. Herein, we developed UV–visible, fluorescence, circular dichroism methods for water detection based on red-emitting chiral carbon dots (RC-CDs). Chiral CDs are generating much interest because of their remarkable optical characteristics, but synthesizing RC-CDs maintaining structures remain challenging terms precursors synthesis methods. In this work, reported new approach via simple solvothermal processing the common l-tyrosine (l-Tyr) o-phenylenediamine (o-PDA) utilizing H2O/H2SO4 as solvent. The as-prepared exhibit an ultranarrow full width at half-maximum (fwhm = ∼27 nm) emission 627 nm with quantum yield 16.2%. Moreover, prepared were applied evaluate multioptical response detect from 10 100% (v/v) ethanol. demonstrate linearity spectroscopy content changes Notably, use through has not been before. summary, believe that work can expand synthetic routes provide early step exciting opportunities design functional chiroptical materials.

Abstract Carbonized polymer dots (CPDs) with a circularly polarized fluorescence property have received increasing attention in recent years. However, it is still great challenge to construct room‐temperature phosphorescence (CPRTP) CPDs. Herein, simple approach the synthesis of intrinsically CPRTP CPDs for first time by utilizing sodium alginate and l ‐/ d ‐arginine as precursors under relatively mild reaction conditions presented. Notably, exhibit both chirality green RTP solid states. Furthermore, color‐tunable successfully achieved engineering chiral light‐harvesting systems based on resonance energy transfer ( C ‐PRET) where function an initiator light absorbance, commercially available fluorescent dyes different emission colors ranging from yellow red serve terminal acceptors. Through one‐step or sequential ‐PRET, can simultaneously furnish transmission/amplification. Given multicolor long afterglow, lifetime‐tunable, properties, their potential applications multiple information encryption are demonstrated.

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.
