“…Moreover, it should be highlighted that using these types of hyperbolic materials, such as carbon nitrides quantum dots, was able to generate improved quantum yields and cell imaging applications. Therefore, for example novel graphitic carbon nitride quantum dots (g-C 3 N 5 -dots) were synthesized using an alkali-assisted hydrothermal method and applied fluorescence probes prepared by an alkali-assisted hydrothermal method, with low cytotoxicity and excellent Biocompatibility for cell imaging [77].…”

In this communication, it was afforded in brief to show how high conjugated carbon based structures, and Carbon allotropes could participate as electron shuttle, semiconductors, quantum emitters and Opto-electronic processors within confined Nanostructured Organized systems. In particular was focused on Nanoassemblies such as vesicles, micelles and lipidic Nanoparticles; and incorporating as well insights from other types of Nanomaterials that could afford to develop new organized systems. It should be noted that in these cases the term organized system was used for all types of molecular assembling and Supramolecular systems that formed structures within the Nanoscale. By this manner the incorporation of Opto-electronic active materials permitted to develop very important photo-physical phenomena with high impact perspectives within technology and Life Sciences. Thus, it was leaded to discuss the participation of Carbon based chemical structures incorporated in different confined molecular media to develop i) Electron Transfer (ET) processes; ii) Reaction Electron Transfers (RET); iii) Catalysis; iv) Quantum emissions; v) Fluorescence Resonance Energy Transfer (FRET); vi) non-classical Light; and vii) Nano-Optics. Therefore, it was intended to present the most important physical and chemical phenomena where they could participate as functional high electronic conjugated chemical structures.

“…Furthermore, a variety of techniques for modifying g-C 3 N 5 have been developed, including element doping, defect engineering, and heterojunction engineering. To date, g-C 3 N 5 -based materials have been widely employed in energy conversion and environmental remediation as a new style of carbon nitride specimen [ 17 , 22 , 23 , 24 ]. However, a comprehensive review of g-C 3 N 5 -based photocatalysts for energy and environmental applications is still lacking.…”

Photocatalysis plays a vital role in sustainable energy conversion and environmental remediation because of its economic, eco-friendly, and effective characteristics. Nitrogen-rich graphitic carbon nitride (g-C3N5) has received worldwide interest owing to its facile accessibility, metal-free nature, and appealing electronic band structure. This review summarizes the latest progress for g-C3N5-based photocatalysts in energy and environmental applications. It begins with the synthesis of pristine g-C3N5 materials with various topologies, followed by several engineering strategies for g-C3N5, such as elemental doping, defect engineering, and heterojunction creation. In addition, the applications in energy conversion (H2 evolution, CO2 reduction, and N2 fixation) and environmental remediation (NO purification and aqueous pollutant degradation) are discussed. Finally, a summary and some inspiring perspectives on the challenges and possibilities of g-C3N5-based materials are presented. It is believed that this review will promote the development of emerging g-C3N5-based photocatalysts for more efficiency in energy conversion and environmental remediation.

Graphitic carbon nitride (g-CN) materials exhibit attractive optoelectronic physical properties; however, their low photoluminescence quantum yields (PLQYs) limit their applications in luminescent devices. Here, boron-doped aromatic carbon nitride (B-PhCN x ) was synthesized for the first time via direct thermal polymerization of 2,4-diamino-6-phenyl-1,3,5-triazine and boric acid. The impact of B doping and phenyl modifying on the structural and optical characteristics of the samples was investigated in detail. The highest PLQY of 40.7% was achieved in B-PhCN 20 , which is 6.8 times that of pristine carbon nitride (p-CN). The B-PhCN 20 -based light-emitting diode demonstrates a maximum luminance of 1494 cd m −2 and a maximum external quantum efficiency of 1.03%, which are 3.5 and 4.9 times that of the p-CN-based device, respectively. Our findings will provide a reference for rationally designing low-cost and high-performance carbon-nitride-based optoelectronic devices.
