[摘要]：The synthesis and evaluation of a novel calix[4]arene-based fluorescent chemosensor 8 for the detection of Cd2+ and Zn2+ is described. The fluorescent spectra changes obsd. upon addn. of various metal ions show that 8 is highly selective for Cd2+ and Zn2+ over other metal ions. Addn. of Cd2+ and Zn2+ to the soln. of 8 results in ratiometric measurement.
