Abstract:

Chemical compounds belonging to the quinone class are known for their cyclic diketone structures. Anthraquinone derivatives have been used as sensing materials and dyes or pigments. The spectroscopic and voltammetric sensing capacity of 1-amino-4-hydroxy-9,10-anthraquinone was utilised to sense 2-bromobenzene-sulfonyl chloride, 4-nitrobenzene-sulfonyl chloride, benzoyl chloride, 2-chlorobenzoyl chloride, and 4-bromobenzoyl chloride. These substituted acyl chlorides and nitrobenzene-sulfonyl chloride are important intermediates in various reactions, and the product formation is highly dependent on their concentration. Therefore, it is crucial to take special care as all these compounds are carcinogenic. All studies were carried out in ethanol solvent. Results showed that 1-AHAQ could be effectively used as a UV–visible sensor for sensing 2-bromobenzene-sulfonyl chloride. 1-AHAQ demonstrates good results as a fluorescence sensor for sensing 4-bromobenzene-sulfonyl chloride and behaves as a good voltammetric sensor for sensing 4-nitrobenzene-sulfonyl chloride.
