Detection of cationic species represents an important field due to its importance in biological and environmental processes. This communication shows the synthesis and application of an ascorbic acid-based quinoxaline derivative (1) in the colorimetric detection of Cu2+ against several other cationic species, including Sr2+, Fe2+, Pb2+, Mn2+, Mg2+, Ni2+, Zn2+, Sn2+, Hg2+, Ca2+, Ba2+, Co2+, Cr3+, Al3+ and Fe3+. Based on experimental and theoretical results, a 1:2 binding model involving 1 and Cu2+ is proposed.
