With the isolation of graphene, there has been a proverbial gold rush in the field of two-dimensional (2D) materials because their unique properties promise numerous applications. The synthesis of 2D materials is currently a hot field with many branches, one of them being synthetic two-dimensional polymers (2DPs). 2DPs share many similarities with other 2D materials but promise tunable properties for various applications. This dissertation focuses on the synthesis and use of monomers that can be fabricated into 2DPs by crystallization or Langmuir-Blodgett approach.Chapter One will explore how 2DPs are classified and showcase some of the current methods for the synthesis of 2DPs. The pros and cons of each method will be highlighted and potential applications of 2DPs will be discussed. Chapter Two describes the synthesis of the monomers fantrip and carboxyfantrip. The fantrip monomer was used in the crystalline-state synthesis of poly(fantrip) and the carboxy fantrip monomer was used in the Langmuir-Blodgett synthesis of poly(carboxyfantrip). The chapter also describes optimization of their syntheses. Chapter Three focuses on the fabrication of poly(carboxy fantrip) by Langmuir-Blodgett techniques. The chapter contains a brief theory behind Langmuir-Blodgett and characterization techniques used on 2DP films. Past and current challenges of using poly(carboxy fantrip) are also present in the chapter.Chapter 4 contains different gas flow measurement through poly (carboxy fantrip). The chapter focuses on using fabricated film for gas flow studies and explains challenges occurred in obtain gas flow data for poly(carboxy fantrip).
