“…However, to the best of our knowledge, g‐C 3 N 4 supported copper chloride (Cu@g‐C 3 N 4 ) material has not been reported in the literature. As a part of continuous interest in the development of heterogeneous synthetic methodologies using nanomaterials, here, we have developed Cu@g‐C 3 N 4 for the [3+2]cycloaddition of nitroolefins/alkynes with sodium azide leading to NH ‐1,2,3‐triazoles (Scheme ).…”

Here, we have reported fabrication of graphitic polymeric C3N4 supported CuCl2 (Cu@g‐C3N4) and characterized by powder X‐ray diffraction, field emission scanning electron microscopy, high resolution transmission electron microscopy, X‐ray photoelectron spectroscopy studies. An efficient and regioselective protocol for the on water synthesis of 4‐aryl‐NH‐1,2,3‐triazole derivatives via 1,3‐diipolar cycloaddition reactions of nitroolefins/phenylacetylenes to sodium azide were demonstrated by using Cu@g‐C3N4 as robust and reusable catalyst.

“…Cu 2 O is a p-type semiconductor material with a narrow bandgap (2.0 eV∼2.2 eV), which has good photoelectric effect properties, like high chemical stability, high direct absorption rate of visible (Vis) light [6][7][8][9][10][11]. Moreover, it is cheap for its abundant reserving on the Earth.…”

Cu2O has the advantages of low price, stable chemical properties, and high visible light absorption rate. It is a very promising hole transport material material in solar cells. However, the pure phase Cu2O has a low hole transport rate, which can be improved it by means of doping or something else. In this paper, based on the first-principles, the performance of different amounts of S, Se, and Te doped Cu2O are calculated, it is found that the Te-doped Cu2O performance is pronounced, with the energy gap reduction (1.871eV), there appear free electron generating, the Highest Occupied Molecular Orbital energy level is matched (-5.463eV), and the absorption coefficient in the ultraviolet and visible range improved, nearly 103.07% at 3.26 eV, the reflectance increased to, for the point 11.7 eV, 76%, and the loss function value is very small in the visible light region (less than 0.1).

“…Some transition‐metal‐catalyzed azo coupling strategies for anilines have been reported, allowing the preparation of azobenzenes with high yields under mild conditions. [ 69 ] Banerjee and co‐workers [ 70 ] reported the selective aerobic oxidative homo/hetero azo‐coupling of aniline in the presence of hierarchical mesoporous RuO 2 /Cu 2 O nanoparticles to prepare symmetrical/unsymmetrical azobenzene compounds without use of oxidants, bases, and additives. In addition, they explored the catalytic and synergistic effects of oxides in the catalyst through DFT calculations and experiments.…”

Azobenzene is a well‐known derivative of stimulus‐responsive molecular switches and has shown superior performance as a functional material in biomedical applications. The results of multiple studies have led to the development of light/hypoxia‐responsive azobenzene for biomedical use. In recent years, long‐wavelength‐responsive azobenzene has been developed. Matching the longer wavelength absorption and hypoxia‐response characteristics of the azobenzene switch unit to the bio‐optical window results in a large and effective stimulus response. In addition, azobenzene has been used as a hypoxia‐sensitive connector via biological cleavage under appropriate stimulus conditions. This has resulted in on/off state switching of properties such as pharmacology and fluorescence activity. Herein, recent advances in the design and fabrication of azobenzene as a trigger in biomedicine are summarized.
