1,4,7,10-tetrakis(2,2'-bipyridyl-5-ylmethyl-bis(2,2'-bipyridine) ruthenium(II))-1,4,7,10-tetraazacyclododecane, a macrocyclic sensor for positively charged species.
The luminescent behavior of the cyclen-based macrocycle L1 was investigated to establish its sensing ability for protons and transition metal ions. It acts as a good pH sensor in the neutral region. Its interaction with Cu (II) and Ni (II) is accompanied by quenching. The rate data for the interaction with Cu (II) were measured at pH 7.43.
