On the basis of an easy access to 2,2′:6′,2″-terpyridine derivatives bearing 6- and 6″-methyl groups, the functionalization of these substituents was investigated. The direct oxidation or bromination of the methyl groups was not feasible on larger scale; however, a two-step process employing oxidation to the pyridine N-oxides followed by acetic anhydride promoted rearrangement (Boekelheide reaction) furnished the corresponding terpyridine derivatives with 6- and 6″-acetoxymethyl groups in reasonable overall yields. These are excellent precursors for the synthesis of tetra- and pentadentate ligands, as demonstrated by several examples. This approach allowed access to a library of new functionalized 2,2′:6′,2″-terpyridine derivatives.

The synthesis and luminescence properties are reported for 20 different chelates composed of 2,2':6',2''-terpyridine as the energy-absorbing and donating group, Eu(III) and Tb(III) as the emitting ions, methylenenitrilo(acetic acids) as the stable chelate
