摘要：

Two novel star-like cyclam derivatives appended with four amino groups and four PEG-arms have been synthesised. The complex formation of cyclam and the two cyclam derivatives with Cu(II) has been studied by UV vis and time-resolved laserinduced fluorescence (TRLFS) measurements outlining 1:1 complexes between cyclam ligands and CU(II). By TRLFS measurements a quench effect of the CU(II) on the fluorescence of the ligand was also found to determine the complex formation between Cu(II) and the ligands. (c) 2005 Elsevier Ltd.
