Synthesis of a novel hexaazatriphenylene derivative for the selective detection of copper ions in aqueous solution.

ABSTRACT: A hexaazatriphenylene (HAT) derivative, naphtho[2,3-h]naphtho[2',3':7,8]quinoxalino[2,3-a]naphtho[2',3':7,8]quinoxalino[2,3-c]phenazine-5,10,15,20,25,30-hexaone (NQH) was synthesized, characterized, and found to have novel properties in being selective toward the detection of copper (Cu²⁺) ions. The capability of NQH to be employed as a colorimetric, chemo-fluorescence and electrochemical sensor for the detection of Cu²⁺ was demonstrated by performing UV-Vis absorbance, fluorescence intensity, and cyclic voltammetry (CV) measurements. The interaction between NQH and Cu²⁺ was initially observed with an obvious color change from yellow to brown upon the addition of Cu²⁺ ions to NQH. The interaction was also confirmed by UV-Vis absorba
