Lanthanide ions possess similar chemical properties, making their separation from one another challenging. Here the authors show that a tris-tridentate ligand causes high-precision metal ion self-sorting, leading to the selective assembly of tetrahed

Metal-halide perovskites-based optoelectronic devices, such as solar cells and light-emitting diodes (LEDs), are transitioning from promising performers to direct competitors to well-established technologies due to the advantage of cost-effectiveness

Modern Aspects of Rare Earths and Their Complexes
This chapter discusses the effects of paramagnetism on nuclear magnetic resonances (NMR) of the ligand molecules by using lanthanide induced shift (LIS). Many lanthanide shift reagents are now available commercially, which are soluble in common organ

This chapter discusses organometallic complexes of rare earths. The 4f orbitals in the lanthanides are well shielded and the metals do not experience an effective nuclear charge as the 5p, 6s, or 5d orbitals. In spite of this, the 4f orbitals become

The lanthanide series of elements differ from the transition metal series in that 4f shell inner electrons are shielded by the 5s 2 , 5p 6 closed shells. Consequently f shell electrons interact much less strongly with their environment than the d ele

This chapter discusses the structural chemistry of lanthanide complexes including their complex formation and coordination number. These factors for rare earth ions are different from those of transition metals. The chemical composition of rare earth
