Post‐Functionalization of Polymers via Orthogonal Ligation Chemistry
摘要
This chapter highlights the current status of critically selected post-functionalization techniques of polymers via orthogonal ligation chemistry, reports the major characteristics of the specific transformation chemistry, and provides the reader useful synthesis-relevant and characterization information. It focuses on the most widely used 1,3-dipolar cycloadditions and Diels-Alder (DA) reactions in polymer chemistry. The chapter then overviews the various ways in which thiols can be used to achieve polymeric post-functionalization. Emphasis is placed upon the ways in which the polymeric materials are prepared to include the required functionality for conjugation and the conditions with which the actual conjugation is carried out. The chapter highlights some elegant examples for the preparation of functional polymers by ring-opening metathesis polymerization (ROMP) via post-modification. It also provides a selection of recent methods in which acyclic diene metathesis (ADMET) can be used for polymeric post-functionalization. Finally, the chapter explains the Pd-catalyzed coupling reactions.
