Heterodinuclear Cryptates [EuML(dmf)](ClO4)2 (M=Ca, Cd, Ni, Zn): Tuning the Luminescence of Europium(III) through the Selection of the Second Metal Ion

“…[38] Recently, many investigations have been done on cryptation-enhanced fluorescence to make chemosensors. [17,31] We use mononuclear Eu III cryptate as a receptor (host molecule) and input a second metal ion as guest species into the host molecule, resulting in a change in the fluorescence intensity of Eu III . The intensities of Eu III can be tuned by the selective introduction of metal ions into the receptor.…”

“…[31] All of them are mononuclear or homodinuclear lanthanide cryptates. There have been few reports on the luminescence properties of heterodinuclear cryptates containing both lanthanide(iii) and other metal ions.…”

Synthesis, crystal structure and properties of two ternary rare earth complexes with aromatic acid and 1,10-phenanthroline

“…Several classes of ligand have been utilized for the preparation of such complexes, such as cryptands [1,2], podands [3,4], ␤-diketones [5][6][7], carboxylic acid derivatives [8][9][10][11][12][13]. Most of them emit red or green light (Eu(III) and Tb(III) luminescence, respectively).…”

Determination of Trace Terbium(III) with N, N, N′-Tri(3-indolemethanal)triaminotriethylamine Based on a New Fluorescence Enhancement System

“…However, their fluorescence properties have rarely been studied due to their low luminescence. 4,5 So far, chemists have realized that it is essential to design appropriate ligands to optimize the luminescence properties of lanthanide ions by facilitating the well-known light conversion process, which that show to be efficient ligand-to-metal energy-transfer process (antenna effect). Recently, we designed a series of Schiff-base ligands having both selective abilities to coordinate lanthanide ions and enhancing their luminescence by providing proper conjugate absorption groups suitable for energy transfer, which could be used as a luminescent device.…”
