Abstract:
The chiral [3+3] macrocycle 1 which displays a calixarene-like crystal structure has been synthesized. The UV/Vis and fluorescence spectral studies show that 1 and Zn²⁺ have a 1:3 complex stoichiometry. It exhibits high selectivity toward Zn²⁺, but no significant responses toward other competitive cations. The intracellular imaging ability has been tested in HeLa cells using a confocal microscope.
