Abstract

LnIII-tripodal Schiff base complex TbIIILtrpn was prepared, in which the three arms of the ligand were extended by one methylene based on the tris(2-aminoethyl)amine in TbIIILtren. TbIIILtrpn showed enhanced TbIII-centered luminescence compared to TbIIILtren. Crystallographic analysis revealed that the symmetry of the seven-coordination environment of the TbIII center in TbIIILtrpn was diminished compared to that in TbIIILtren, resulting in the increased radiative transition rate and/or decreased back energy transfer rate and, thus, the increased luminescence.
