“…Their emission peak was at 405 nm, and their chirality could be regulated by adjusting the reaction time. However, despite such encouraging progress, there are few reports regarding, for example, the challenging preparation of red‐emitting and wavelength‐tunable Ch‐CPDs [2a, 9] . Three factors are key for the synthesis of red‐emitting CPDs: (1) precursors, (2) reaction temperature, and (3) reaction solvents [10] .…”

“…More recently, efforts have also been made to develop chiral carbon dots for their application in a myriad of exciting areas ranging from sensing of chirality, separation of chiral molecules, chiral catalysis, bioimaging, and biomedicine. Among the two types of CD synthesis approaches, the “bottom-up” approach usually generates better chiral CDs as the precursor molecules themselves are chiral and therefore do not need the introduction of chiral ligands during the synthesis process [ 87 ]. A hybrid CD/CNC (cellulose nanocrystal) nanoparticle synthesized via hydrothermal route showed a dissymmetry factor of 0.2, which is higher than that of the reported dye/CNC hybrids.…”

Carbon dots (CDs) are optically active carbon-based nanomaterials. These nanomaterials can change their light emission properties in response to various external stimuli such as pH, temperature, pressure, and light. The CD’s remarkable stimuli-responsive smart material properties have recently stimulated massive research interest for their exploitation to develop various sensor platforms. Herein, an effort has been made to review the major advances made on CDs, focusing mainly on its smart material attributes and linked applications. Since the CD’s material properties are largely linked to their synthesis approaches, various synthesis methods, including surface passivation and functionalization of CDs and the mechanisms reported so far in their photophysical properties, are also delineated in this review. Finally, the challenges of using CDs and the scope for their further improvement as an optical signal transducer to expand their application horizon for developing analytical platforms have been discussed.

Light‐emitting chiral carbonized polymer dots (Ch‐CPDs) are attracting great interest because of their extraordinary photonic properties, but modulating their band‐gap emission, especially at long wavelength, and maintaining their chiral structure to achieve multicolor, high‐emission Ch‐CPDs remains challenging. Reported here for the first time is the synthesis of red‐ and multicolor‐emitting Ch‐CPDs using the common precursors L‐/D‐tryptophan and o‐phenylenediamine, and a solvothermal approach at one temperature. The quantum yield of the Ch‐CPDs was between 31 % and 54 %. Supramolecular self‐assembly provided multicolor‐emitting Ch‐CPDs showing novel circularly polarized luminescence, with the highest dissymmetric factor (glum) of 1×10−2. Importantly, circularly polarized white‐emitting CPDs were fabricated for the first time by tuning the mixing ratio of the three colored Ch‐CPDs in a gel. This strategy affords exciting opportunities for designing functional chiroptical materials.
