The present article describes synthesis, characterization and a detailed complexation study of calix [4]arene based chemosensor (4) bearing two anthracenyl units as signaling groups on its coordination sphere. The complex formation ability of 4 toward selected transition metals such as Cd(II), Co(II
## Abstract A new neutral fluorescent chemosensor 5 based on a calix[4]arene tetraamide derivative has been synthesized. It exhibits high selectivity for H~2~PO~4~^โ^ over a wide range of anions, and the selectivity for H~2~PO~4~^โ^ is more than 2700โfold higher than for F^โ^. In acetonitrile, the
