초록/해제  
요약Metal-free ring-opening metathesis polymerization (MF-ROMP) is an efficient route to achieving high-value linear polymers equivalent to those made using metal-mediated ROMP. Because MF-ROMP eliminates the need for transition metal-based initiators by instead using an organic enol ether initiator activated by a pyrylium photocatalyst, the applications of polymers made using this technique can be expanded into areas previously inaccessible to ROMP-based polymers, including biomedical and electronic applications where residual transition metals can be detrimental to the environment in which they are used. However, the low functional-group tolerance of MFROMP has made synthesis of structurally useful polymers challenging. In this research the orthogonality of MF-ROMP towards various functional groups is explored, which can allow for the synthesis of completely metal-free polymers for various applications.The work presented in this dissertation seeks to leverage the very facets of the polymerization that differentiate it from traditional metal-mediated ROMP, namely its completely organic components, and its ability to selectively ring-open some cyclic olefins while leaving others untouched. Chapter 1 of this thesis will contextualize MFROMP within the broader scope of ROMP, as well as other metal-free controlled polymerizations. In Chapter 2, commercially available chain-transfer agents are presented as a chain-end functionalization strategy. Further, custom chain-transfer agents and initiators are leveraged in Chapter 3. Chapter 4 exemplifies the utility of a particular functional initiator identified in Chapter 3 as a highly efficient way to make all-ROMP graft-through bottlebrush polymers. Lastly, Chapter 5 uses post polymerization modification strategies to functionalize MF-ROMP polymers towards metal surface functionalization.
