Magnetic polymers overview

Modification of the ligand denticity (pentadentate instead of hexaden-tate) allows the assembly of nd-4f helicates which exhibit a rich variety of magnetic and spectroscopic properties combining the intrinsic features of both types of metal ions thanks to intermetallic communication within the helical molecules. The overview ends by describing helical structures foimd in coordination polymers, as well as some 5f helicates.

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. 

This section provides a broad overview of the application of NMR spectroscopy to crystallinity determination in polymers. The approaches illustrated are certainly not exhaustive of those available for the powerful NMR technique and the interested reader is encouraged to consult one or more of the reference books on NMR spectroscopic investigations of polymeric materials (51-53) (see NUCLEAR Magnetic Resonance). 

This chapter provides an overview of MNP-polymer composite self-assembly and the future technologies and applications associated with recent developments in the field. We first provide a general overview of magnetism and the distinction between SPMNPs and FMNPs. This section is followed by a discussion of the formation of one-, two-, and three-dimensional composite assemblies. Within the discussion, the strategies that employ synthetic polymers and biopolymers for coassembly with MNPs are described. This chapter also describes promising future technologies that utilize some of the most recent advances in the self-assembly of MNP-polymer composites. 

Abstract The scientific community tries to mimic nature in the way that living organisms adopt their behavior as a function of environmental conditions to improve survival. In this sense, smart polymers offer materials that respond to numerous stimuli (temperature, pH, electric and magnetic fields, light intensity, biological molecules, etc.), and scientists must devise the best way to apply them in all research areas. This chapter comprehensively summarizes the content of this book which tries to provide a wide overview of smart polymers and the most interesting applications developed recently.
