The self-assembly and rheological studies of self-healing Eu( iii) luminescent metallogels from a btp (2,6-bis(1,2,3-triazol-4-yl)pyridine) ligand is described.
The synthesis of five new 2,6-bis(1,2,3-triazol-4-yl)pyridine ( btp) ligands is described: the self-assembly behaviour of the tri-methyl ester, 1, with Eu( iii) showed the formation of a luminescent 1 : 3 Eu : btp complex, Eu13, which was studied in solution and in the solid state; while the tri-carboxylic acid, 2, formed a hydrogel and its corresponding complex Eu23, gave rise to a strongly red luminescent healable metallogel.
