Abstract

The hypothesis of trans complex aggregation finds additional support in the time-resolved fluorescence experiments. In Table I11 are presented fluorescence decay parameters for trans-L and its complexes with Mg2+, Ca2+, and BaZ+. Upon excitation at 355 nm by a 8-ps laser pulse, emission was detected at wavelengths above 480 nm. The decay of the free ligand is purely monoexponential with a lifetime of 137 ps, in good agreement with the ...
