title: One-step heterylation at the upper rim of calix[4]arene with 1,2,4-triazin-5(2H)-ones.
abstract: A convenient way to modify calix[4]arenes based on the direct C-C coupling reaction of their phenol moiety with 1,2,4-triazines has been advanced, and the ability of modified calixarenes to provide transport of La3+ and Ga3+ cations through organic membranes has been examined.
