Carbon dots‐involved chemiluminescence: Recent advances and developments

Abstract

In recent years, more and more nanomaterials‐based chemiluminescence (CL) systems have appeared to improve the sensitivity and expand the scope of the analytical applications with the explosive growth and development of nanomaterials and technology. As a fascinating class of luminescent carbon nanomaterials, carbon dots (CDs) are now substantially studied in fabricating CL based assays due to their unique optical and mechanical properties. Herein, we summarize and highlight the current developments of CDs‐involved weak or ultraweak CL systems, as well as the corresponding mechanisms and proper applications in some fields. CDs can take part in the CL reactions as oxidants, emitting species directly involved in redox oxidation, energy acceptors of CL energy transfer, or even catalysts involving other luminophores. In fact, they always have more than one role in many cases, owing to the formation of various excited species with short life in CL systems. Therefore, in this review article, the most recent progress of the different CDs‐assisted CL systems including the mechanisms and applications are presented. Finally, the conclusions and future prospects of this field are also discussed. The significant features of the CDs‐based CL systems may open up new prospects and challenges in a wider range of fields.

Flexible and Robust Electro‐Optically Responsive Films Based on Novel Silica/Oligoaniline/Carbon Dots Composite

“…[5][6][7][8] While these materials offer extraordinary properties, production scale manufacturing of devices based on many of these materials remains a chemistry and engineering challenge due to a variety of factors. [11][12][13][14][15][16] Oligoanilines, as model compounds of polyaniline, have garnered significant interest due to interesting and predictable electroactive properties and potential applications in anticorrosion, sensors, tissue engineering, and energy-related fields. We surmised it might be possible to create composite films with properties similar to organic electronic materials by decorating electroactive components with ortho silicates units, cast them on an ITO surface, and crosslink the ortho silicates hydrolytically.…”

“…[11][12][13] Generally, CDs are composed of inner sp 2 -hybridized carbon atoms, outer sp 3 -hybridized carbon atoms, and surface oxygen-containing functional groups such as amino, epoxy, ether, carbonyl, hydroxyl and carboxylic acid groups, thus making them possess excellent water solubility, easily tunable surface functionalization or subsequent labels with various chemical species.

“…To these ends we chose a combination of oligoanilines (based on our previous work) [9,10] and carbon dots (chosen for a number of reasons highlighted below).

[17][18][19][20][21] Introducing oligoanilines in a variety of polymeric architectures can endow them with attractive electroactivity and stimuli-responsiveness, while featuring superior solubility, processability, and tunability.…”

“…Carbon dots (CDs), as new emerging fluorescent carbonaceous nanomaterials, have likewise received significant research interest in recent years, related in large part to their advantages over metal-based quantum dots such as low toxicity, tunable fluorescence, improved water solubility and unique physicochemical properties. [11][12][13] Generally, CDs are composed of inner sp 2 -hybridized carbon atoms, outer sp 3 -hybridized carbon atoms, and surface oxygen-containing functional groups such as amino, epoxy, ether, carbonyl, hydroxyl and carboxylic acid groups, thus making them possess excellent water solubility, easily tunable surface functionalization or subsequent labels with various chemical species. [14][15][16] In view of the fluorescence and tunable surface characteristics of CDs, we surmised that a new hybrid material could be generated through covalent bonds between oligoanilines and CDs.…”
