The Development Of Photoinduced Initiation Of Olefin Polymerization And Its Applications, Justin M. Burroughs
Doctoral Dissertations
Polyolefin synthesis is an ever-growing field due to the low cost of monomer feed stocks and the wide range of applications of the resulting polymeric material. Polyolefins are most commonly polymerized through coordination-insertion polymerization. One area this field of research has progressed is the development of complex ligand scaffolds to achieve various levels of control over polymerization. For example, researchers have been able to control molecular weight, branching density, and tacticity of various olefin polymerizations. As a result of complex ligand scaffolds, the catalytic systems become more expensive and less industrially applicable. On the other hand, little research efforts have …

Simplified Synthesis Of Conjugated Polymers Enabled Via 1,4-Dihydropyrrolo[3,2-B]Pyrrole, Kenneth-John Jack Bell
Master of Science in Chemical Sciences Theses
Conjugated polymers have attracted significant attention as the active layer material in organic electronics, such as organic photovoltaics and light-emitting diodes, partly due to the ability to influence a broad range of properties through structural design motifs. However, high performance conjugated polymers suffer from numerous synthetic steps, generation of toxic waste, and harsh reaction conditions all of which impart additional costs that inhibit their widespread utilization. Therefore, an emphasis on reducing synthetic complexity and utilizing abundant, commercially available starting materials is needed for organic electronics to reach their full potential. Dihydropyrrolo[3,2-b]pyrrole (H2DPP) chromophores offer a simple one-pot synthesis …
