Recent advances in fluorescence chemosensors for ammonia sensing in the solution and vapor phases

Chemical Communications, Journal Year: 2023, Volume and Issue: 59(13), P. 1728 - 1743

Published: Jan. 1, 2023

Developing low-cost and reliable sensor systems for the detection of trace amounts toxic gases is an important area research. Ammonia (NH3) a commonly produced industrial chemical harmful colorless pungent gas released from various manufacturing processing industries. Continuous exposure to NH3 vapor causes serious menace human health, microorganisms, ecosystem. Exposure relatively higher concentrations severely affects respiratory system leads kidney failure, nasal erosion ulcers, gastrointestinal diseases. Excessive accumulation in biosphere can cause metabolic disruptions. As consequence this, therefore, suitable sensing methods selective quantification are utmost need protect environment living systems. Given there have been significant research advances preceding years on development fluorescence chemosensors efficient monitoring concentration both solution phases. This review article highlights several reported until recently quantifying phase or ammonium ions (NH4+) phase. The wide variety discussed this systematically gathered according their structures, functional properties, properties. Finally, usefulness existing challenges using fluorescence-based method future perspective also highlighted.

Multicomponent Synthesis of Imidazole‐Linked Fully Conjugated 3D Covalent Organic Framework for Efficient Electrochemical Hydrogen Peroxide Production

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(49)

Published: Oct. 26, 2023

The semiconducting properties and applications of three dimensional (3D) covalent organic frameworks (COFs) are greatly hampered because their long-ranged non-conjugated skeletons relatively unstable linkages. Here, a robust imidazole-linked fully conjugated 3D framework (BUCT-COF-7) is synthesized through the one-pot multicomponent Debus-Radziszewski reaction saddle-shaped aldehyde-substituted cyclooctatetrathiophene, pyrene-4,5,9,10-tetraone, ammonium acetate. BUCT-COF-7, as metal-free catalyst, shows excellent two electron oxygen reduction (ORR) activity in alkaline medium with high hydrogen peroxide (H2 O2 ) selectivity 83.4 %. When BUCT-COF-7 cathode catalyst assembled into electrolyzer, devices showed electrochemical production rate H2 up to 326.9 mmol g-1 h-1 . accumulative amount could totally degrade dye methylene blue via Fenton for wastewater treatment. This first report about intrinsic COFs efficient synthesis , revealing promising environment-related field.
