    Abstract: The present invention relates particularly to novel preorganized hexadentate ligands that are suitable for complexing with a radionuclide, and are useful as general imaging agents for diagnostic purposes. They have general formula (I), wherein R1 and R3 are the same or different and are selected from the group consisting of hydrogen, alkyl, aryl hydroxyl, alkoxyl, mono- or poly- hydroxyalkyl, mono- or poly- alkoxyalkyl, alkoxycarbonyl or carbamoyl; l and m may be the same or different and are from 2 to 5; Q and Z may be the same or different and are an O, N or S atom; and X and Y may be the same or different and are selected from the group consisting of (a), wherein R4-R6 may be the same or different and are selected from the group consisting of hydrogen, alkyl, aryl, hydroxyl, alkoxyl, mono- or poly- hydroxyalkyl, mono- or poly- alkoxy-alkyl, alkoxycarbonyl, amino, alkylamino, aminoalkyl, or carbamoyl.
