Encapsulation of the chelates into nanopartieles often results in further improvements of their photophysical properties [219,220]. We have also seen above that relatively modest quantum yields can be compensated by introducing several emitting ions in one probe. This is achieved in luminescent metal-organic frameworks [221] or dendrimeric complexes [214] which then present attractive properties, including multifunctionality and nanoscale processability, for chemical sensors and bioprobes.

In addition, Qian and coworkers reported a luminescent lanthanide-based metal-organic framework (MOF) [Eu(L16)i.5(dmf)]-(DMF)o.5(H20)o.5 (Eu-17, L17vpyridine-3,5-dicarboxylate) with Lewis basic pyridyl sites for the sensing of metal ions (Cu +, Co +, and so on) [40], Under excitation at 321 nm, Eu-17 shows characteristic emission bands of the Eu + ion at 590, 616, and 698 nm, which were ascribed to transitions from the Dq state to " Fi, " F2, and " F4, respectively. The luminescence intensity of Eu-17 was strongly dependent on the identity of the metal ion, with Cu + having the most significant quenching effect. Moreover,...

This volume of the Handbook on the Physics and Chemistry of Rare Earths adds five new chapters to the science of rare earths, compiled by researchers renowned in their respective fields. Volume 34 opens with an overview of ternary intermetallic systems containing rare earths, transition metals and indium (Chapter 218) followed by an assessment of up-to-date understanding of the interplay between order, magnetism and superconductivity of intermetallic compounds formed by rare earth and actinide metals (Chapter 219). Switching from metals to complex compounds of rare earths, Chapter 220 is dedicated to molecular stmctural studies using circularly polarized luminescence spectroscopy of lanthanide systems, while Chapter 221 examines rare-earth metal-organic frameworks, also known as coordination polymers, which are expected to have many practical applications in the future. A review discussing remarkable catalytic activity of rare earths in site-selective hydrolysis of deoxyribonucleic acid (DNA) and ribonucleic acid, or RNA (Chapter 222) completes this book. 

As multidentate ligands, s-tetrazines successfiilly find application in coordination chemistry. Their derivatives are useful building blocks for metal-organic frameworks (MOFs). Thus, the first example of an MOF with the novel 3,3 -(l,2,4,5-tetrazine-3,6-diyl)dibenzoic spacer 57 was reported and its luminescence and adsorption properties were studied (13IC546). Complexation of Sm(III) with 2,6-bis(4-npropyl-2,3,5,6-tetrazine-l-yl)pyridine 58 as an analog of BTP was studied using time-resolved laser fluorescence spectroscopy (13DT12139).
