In the fields of biologically active materials and functional materials, fluorinated organic materials are becoming a focus of significant interest. Over the past decade synthetic methodologies and reagents in fluorine chemistry have been developed, especially stereocontrolled synthetic methods, enzymatic resolution to synthesize enantiomers, fluoromethylated reagents, and fluorination reagents. These methods have contributed to the opening of new pathways for fluorinated materials. However, few fluorinated materials have been put to commercial use. Furthermore, there remain problems to be solved, such as the handling of the materials, availability of reagents and selectivity (stereo-, regio-, and/or chemoselectivity). Research chemists, technical engineers, and graduate students in all branches of chemistry, pharmaceutics, and material science interested in fluorinated materials need to know detailed experimental procedures of how to synthesize the target fluorinated materials.This volume summarizes the chemical and microbial methods for obtaining functionalized fluorinated materials for use as building blocks; detailed experimental methods (reaction conditions, solvent, temperature, handling techniques, etc.); and the stereoview (possible absolute configuration) of the structures with spectral data. Mono-, di-, tri-, and polyfluorinated materials derived from fluorinating agents, fluoromethylated reagents and building blocks are summarized. A chemical name index, molecular formula index, and reagent index are also included. The publication of this monograph will provide access to the enormous possibilities in fluorine chemistry, biological material chemistry, and functionalized material chemistry.

This book investigates various aspects of East Asia’s borders and borderlands and contextualizes them in the region's dynamic geopolitical and geoeconomic contexts. It illustrates how a regional or trans-border framework for border studies can deepen our understanding of borders and borderlands and guide us in a better direction of research and practice. While the introductory chapter argues for the importance of contextualizing borders from an appropriate theoretical framework built on preceding works, four empirical chapters focus on border issues in China, North Korea, Okinawa, Taiwan, and Hong Kong, showing that East Asia, particularly the East China Sea region, consists of non-conventional borders and that deviations from the Westphalian sovereign territory characterize East Asian borderlands. This book persuasively demonstrates how the 'contextual theorization' of borders in East Asia becomes possible by identifying the common aspects shared by these empirical cases.Spanning the broad subject areas of political geography, international relations, Asian studies, and border studies, this comprehensive work serves as an essential resource for students, scholars, researchers, and practitioners seeking to understand the complexities of East Asian geopolitics, while also providing valuable insights for policymakers and analysts working on regional security and trans-border governance issues.The chapters in this book were originally published as a special issue of Geopolitics.
