Luminescent (metallo-supramolecular) cross-linked lanthanide hydrogels from a btp (2,3-bis(1,2,3-triazol-4-yl)picolinamide) monomer give rise to strong Tb(<scp>iii</scp>) and Eu(<scp>iii</scp>) centred emissions

Abstract

The synthesis and study of the lanthanide luminescent 2,3-bis(1,2,3- triazol-4-yl)picolinamide (btp) based hydrogels F1 and F2 is described where Tb( iii ) or Eu( iii ) are also used to crosslink the btp units within the polymers.
