Abstract: Three new fluorescent probes based on C3v symmetric calix[6]arene functionalized with three anthracylselenoalkoxy (1), anthracyltelluroalkoxy (2) or anthracylthiaalkoxy (3) groups were synthesized, respectively. The photophysical behavior and the binding ability of 1-3 with some alkaline metal ions and transition metal ions were investigated by fluorescence spectrometry. Receptor 1 exhibited highly selective fluorescence quenching behavior towards Hg2+ in CH2Cl2 with Ka = (1.12 ? 0.08) ? 105 M-1. In addition, the color change of 1-Hg2+ from colorless to light yellow allows naked-eye detection of mercury (Ⅱ)
