    • F = 0.36] [23]. The absorption and fluorescence titrations were performed by adding microlitre amounts of acetonitrile or ethanol solutions of the corresponding titrating agent to dichloromethane solutions of the ligand. Dynamic coordination experiments were performed by adding 1 equiv. of the corresponding metal ion to a dichloromethane solution of the ligand, and recording the absorption spectrum of the resulting solution at different times. Organic reagents and transition-metal salts were supplied by Aldrich and used without further purification. Dichloromethane and acetonitrile UV-sol (MERCK) were used as solvents for the spectrophotometric and spectrofluorimetric measurements without further purification. Elemental analyses were performed on a Carlo Erba EA-1108 instrument by the Chemical Analysis Service of the Universitat Autònoma de Barcelona, Bellaterra, Spain. NMR spectra were recorded on a Bruker 250 MHz AC instrument. Mass spectra were recorded using a HP298S gas chromatography/mass spectrometry (MS) system.
