Unassymetric bis[2-(2′-hydroxyphenylbenzoxole)] bis(HBO) derivatives with a DPA functionality for zinc binding have been developed with an efficient synthetic route, using the retrosynthetic analysis. Comparison of bis(HBO) derivatives with different substitution patterns allows us to verify and optimize their unique fluorescence properties. Upon binding zinc cation, bis(HBO) derivatives give a large fluorescence turn-on in both visible (λem ≈ 536 nm) and near-infrared (NIR) window (λem ≈ 746 nm). The probes are readily excitable by a 488 nm laser, making this series of compounds a suitable imaging tool for in vitro and in vivo study on a confocal microscope. The application of zinc binding-induced fluorescence turn-on is successfully demonstrated in cellular environments and thrombus imaging.

Methods for preparing 2,5-Bis(benzoxazol-2′-yl)benzene-1,4-diol derivatives (Zinhbo derivatives) are provided. 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.
