Synthesis, Characterization And Application Of Structurally Diverse Poly(Chalcogenylene Vinylene)S, Zhen Zhang

Chemistry and Chemical Biology ETDs

Conjugated polymers have found widespread applications in flexible and printable electronic devices, among which poly(thienylene vinylene) (PTV) displays outstanding optoelectronic properties and promising applications. However, further studies of its structure-property-function relationship have been greatly impeded mainly due to the synthetic difficulty of generating new structures beyond its rudimentary form.

To further investigate this class of material, I have developed a facile methodology for the preparation of structurally diverse poly(chalcogenylene vinylene)s (PCVs) through a combination of acyclic diene metathesis (ADMET) polymerization and post-polymerization modification techniques. Specifically, a series of halogenated and cross-conjugated PCVs have been designed and synthesized, followed by complete …
