Generating water/MeOH-soluble and luminescent polymers by grafting 2,6-bis(1,2,3-triazol-4-yl)pyridine (btp) ligands onto a poly(ethylene-alt-maleic anhydride) polymer and cross-linking with terbium(iii)

Abstract

The synthesis of two new polymers made from P(E-alt-MA) (poly(ethylene-alt-maleic anhydride) and possessing 2,6-bis(1,2,3-triazol-4-yl)pyridine (btp) ligand side chains in 3 and 6 mol%, respectively (P1 and P2, respectively) is described....

Formation of lanthanide luminescent di-metallic helicates in solution using a bis-tridentate (1,2,3-triazol-4-yl)-picolinamide (tzpa) ligand

“…With the view of extending the scope of using the f-metal ions in the coordination driven self-assemblies, we have also developed several examples of ligands based on the 2,6-bis(1,2,3-triazol-4-yl)pyridine ( btp ) motif, 20 which included their applications in the formation of MOFs 21 and lanthanide cross-linked hydrogels. 22 Both pda and btp are versatile building blocks, which can form 1 : 3 (M : L) coordination complexes with the lanthanides completing their high coordination requirements (normally of nine), as each ligand is tridentate. 23 With that in mind we recently combined these two coordination environments within a single ligand motif, the result being the formation of a new class of bis-tridentate (1,2,3-triazol-4-yl)-picolinamide ( tzpa ) ligands.…”
