Dudina, E. Antina, D. Sozonov, A. V'yugin] New "off-on” Zn2+ fluorescent probes in organic solvents were developed underlain by ligands consisting of deca-, octa-, and tetramethyl-substituted 3,3′-bis(dipyrrins). The coordination of the probes with two Zn2+ ions with the formation of complexes [Zn2L2] is accompanied with a significant (200-550-fold) increase in the fluorescence intensity. The fluorescence response is maximum for the reaction of Zn2+ with tetramethyl-substituted 3,3′-bis(dipyrrin). The presence of cations of Na+, Mg2+, Mn2+, Co2+, Ni2+, Cd2+, Hg2+, and other metals, save Cu2+, does not interfere with the detection of Zn2+ demonstrating the high selectivity of bis(dipyrrin) Zn2+-sensors.
