Lanthanide-containing functional materials are an important class of compounds with interesting chemical properties. Lanthanide f-electrons give rise to interesting magnetic and photoluminescence properties that make these materials optimal for single-molecule magnets, magnetocaloric effect, and light emitting diodes. Lanthanides have a flexible coordination sphere that allows production of multiple structure types. The incorporation of Ni2+ and Ln3+ into the same structure expands the study of these properties. The work herein focuses on both the synthetic approach to and properties of novel lanthanide metal-organic frameworks, gigantic heterometallic clusters, and nanomaterials.

520 $a Lanthanide-containing functional materials are an important class of compounds with interesting chemical properties. Lanthanide f-electrons give rise to interesting magnetic and photoluminescence properties that make these materials optimal for single-molecule magnets, magnetocaloric effect, and light emitting diodes. Lanthanides have a flexible coordination sphere that allows production of multiple structure types. The incorporation of Ni2+ and Ln3+ into the same structure expands the study of these properties. The work herein focuses on both the synthetic approach to and properties of novel lanthanide metal-organic frameworks, gigantic heterometallic clusters, and nanomaterials.
520 $a Chapter 1 provides a fundamental background of lanthanides, properties of lanthanides, lanthanide-based materials, and potential applications of lanthanide-containing materials. This chapter gives a summary of synthetic approaches and methods for understanding the properties of these unique metal materials.
520 $a Chapter 2 discusses the synthesis and structural characterization series of a 2D lanthanide metal-organic frameworks. These metal-organic frameworks were produced under ambient conditions. Eu3+ and Tb 3+ were doped into the parent metal-organic framework without disruption of the framework. Tunable luminescence was achieved by the production of five mixed Eu/Tb metal-organic frameworks.
520 $a In chapter 3 two novel lanthanide metal-organic frameworks are structurally characterized and studied for proton conduction. These include a 2D cerium metal-organic framework and a series of 3D lanthanide metal-organic frameworks with hydrophilic channels and pores respectively with interchelated water molecules allowing for a proton conduction pathway. The proton conductivities of these metal-organic frameworks were analyzed using pellets and single crystal samples. The proton conduction was determined via activation energy to follow a Grotthus mechanism.
520 $a Chapter 4 focuses on the synthesis and structural characterization of novel gigantic 3d-4f clusters. A range of clusters using Ni2+ and Ln3+ (Ln=Er, Ho, Dy, Gd, Sm, Eu, Nd, Pr, and La) were produced under hydrothermal conditions and iminodiacetic acid as the supporting ligand. This novel cluster series of Ni2+ and Ln3+ revealed an interesting trend based on the atomic radius of Ln3+ ion utilized. When incorporating a larger Ln3+ ion, a larger cluster with more Ni2+ ions is obtained. The magnetic studies of Er3+ cluster showed significant magnetic anisotropy and/or population of low-lying excited states.
520 $a Chapter 5 explores a facile hydrothermal synthetic approach to porous and non-porous lanthanide hydroxide nanorods. These nanorods were characterized using powder X-ray diffraction and transmission electron microscopy. These nanomaterials have potential use as catalysts, magnetic resonance imaging contrast agents, and drug delivery systems.
520 $a The final chapter summarizes the importance of the presented novel lanthanide-containing materials. The work herein shows the use of multiple synthetic approaches and methods of testing lanthanide-based functional materials for potential applications in solid state light emitting devices, magnetic cooling, and single-molecule magnets. This chapter also discusses potential expansion of these projects for future experiments.
520 $a Appendices A, B, C, and D provide the supporting information for these projects. Appendix A contains single-crystal X-ray diffraction information. Appendix B entails excitation and emission scans for all mixed Eu/Tb metal-organic frameworks presented in chapter 2. Appendix C provides an additional Ln coordination polymer referenced in chapter 3. Appendix D provides the experimental powder X-ray diffraction patterns for clusters 1--5 and 7--13 from chapter 4.
