Oxidation of poly(enetetramine)s: a new strategy for the synthesis of conjugated polyelectrolytes

摘要

Chemical oxidation of poly(enetetramine)s was demonstrated as a new synthetic route to prepare conjugated polyelectrolytes.rnConjugated polymers (CPs) came into prominence nearly 20 years ago with the discovery that poly(p-phenylene vinylene) could be used in organic light-emitting diode applications. Since then, CPs have been implemented in diverse fields ranging from sensors to electronics. As a subclass, conjugated polyelectrolytes are emerging as valuable materials for sensing ionic analytes, such as nucleobases and DNA, as well as in photovoltaic devices and semiconductors. Although these polymers can possess charges either as integral components of their main chains or pendants thereof, the former type has received far less attention. This deficit is primarily due to inherent synthetic limitations, which typically involves adding charge to already-formed polymers (e.g., exhaustive alkylation of neutral heteroaromatics).
