AB The present work describes the synthesis of the new Schiff base H2L, containing atrypticene residue, and its reactivity towards niquel(II), copper(II), zinc(II), palladium(II),silver(I) and cadmium(II). This study discusses the reaction conditions that allow isolatingtrinuclear Zn and Ni complexes. The experimental requirements to obtain coordinationcompounds with the remaining metal ions, although sought, could not be set. Analyticaland spectrometric characterization of the Zn and Ni compounds completely agrees with thetrinuclear nature of the complexes.The fluorescence study of the ligand in solution, both as free ligand and in thepresence of ZnII and NiII, shows that H2L is fluorescent and that the presence of the metalions partially quenches the fluorescence emission of the ligand itself. Thus, given thevariation of the luminescence properties in the presence of metal ions, the ability of H2L toact as a luminescence chemosensor was investigated. The results show that theexperimental conditions tested do not permit to stabilize the optical response of the ligandin the presence of metal ions.In addition, H2L was checked as an absorbance chemosensor, and in this case theresults demonstrate that it can be used to quantify the presence of Zn2+ and Ni2+ in themedium.
