wherein
L1 is (PRaRb);
L2 is (PRaRb);
L3 is CO;
L4 is CO;
L5 is absent or CO;
Z represents zero, one, two or three substituents wherein each such substituent is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heterocyclyl, heteroaryl, alkylcycloalkyl, alkylaryl, alkylheterocyclyl, alkylheteroaryl, halogen, nitro, amide, ester, cyano, alkoxy, alkylamino, arylamino, an inorganic support and a polymeric moiety; or Z forms a fused aromatic or heterocyclic ring with the nitrogen based ring;
Ra and Rb are each independently alkyl, cycloalkyl, aryl, heterocyclyl, heteroaryl, alkylcycloalkyl, alkylaryl, alkylheterocyclyl or alkylheteroaryl.
