Insight on spectral, thermal and biological behaviour of some Cu(II) complexes with saturated pentaazamacrocyclic ligands bearing amino acid residues

A novel series of Cu(II) complexes with formula M(HL n )(ClO 4 ) 2 ·mH 2 O [HL n : 13-membered pentaazamacrocyclic ligand resulted from condensation of N , N ′-bis(2-aminoethyl)ethane-1,2-diamine, l -tyrosine (HL 1 )/ l -tryptophan (HL 2 )/ l -phenylalanine (HL 3 ) and formaldehyde] were synthesized...
