Polymerization Mechanisms and Thin Film Deposition

This lecture covers the proposed mechanisms of Wittig polycondensation and electrochemical thiophene polymerization, as well as the synthesis of poly(alkylthiophene)s using Rieke methods. It also discusses the regioregularity of poly(3-alkylthiophene)s, the oxidative polymerization of pyrrole and thiophene derivatives, and the synthesis of regioregular poly(3-alkylthiophene)s via the McCullough Route. Furthermore, it explores the structure and properties of poly(thiophene)s, the synthesis of soluble pentacenes, and the frontier orbital participation in Diels Alder reactions. The lecture concludes with insights into inorganic vs. organic electronics, organic thin film deposition methods, and thin film growth phenomena in vapor phase deposition.
