- 요약Two-dimensional polymers (2DPs), or 2D covalent organic frameworks, are crystalline and porous polymers linked by covalent bonds. Although 2DPs show great promise in many areas, their applications are mostly limited due to their aggregate powder forms and unexplored classes of functional monomers. In this thesis, I discuss work that has overcome these limitations through improved thin film synthetic conditions, improved colloidal syntheses, and incorporation of phenazine units into 2DPs.In Chapter 1, I define and describe the synthesis, characterization, and applications of 2DPs with a particular emphasis on their colloidal stabilities for processable inks and thin film applications. In Chapter 2, I describe our work in the development of a facile and modular approach to printing 2DP thin films with programmable designs for the printing of highly resolved thermal sensors that outperform other analogous solution-processable polymers. In Chapter 3, I analyze and report the thermal conductivities of 2DPs containing different chemical linkages. This study provides insight into the structure-property relationships between the thermal phonon processes involved in heat transfer through a 2DP versus non-crystalline polymeric thin films. In Chapter 4, I detail the development of a phenazine-containing 2DP for the photoreduction of carbon dioxide to carbon monoxide, formate, and oxalate. This is the first example of a metal-free polymer catalyzing the formation of oxalate as a fuel from carbon dioxide. An examination of the band gaps, catalytic mechanism, and performance is discussed.Taken together, this thesis explores structure-property relationships in two-dimensional polymers, in addition to highlighting their modularity, applications, and exceptional properties. It also takes a critical look at limitations and opportunities in next-generation 2DPs.
