Abstract
2,5-Bis(benzoxazol-2′-yl)benzene-1,4-diol derivatives (Zinhbo derivatives) are used to detect zinc ions and have particular application in vivo and in vitro. Zinhbo derivatives upon excitation give a florescence response emission that can be used to determine the presence of zinc cation in solution. Zinhbo derivatives complexed with zinc cations upon excitation can produce a florescence response emission in the visible and near infrared range. Zinhbo derivatives complexed with zinc cations exhibit a large stoke shift between the excitation and emission wavelengths.
