Exploring the Synthesis of Triptycene-Based Polymer Building Blocks and Their Related Phosphorus-Rich Polymer Networks.
Abstract
This dissertation describes research that delves into synthesizing and characterizing polymer building blocks derived from triptycene for the creation of phosphorus-containing polymer networks in wastewater purification. The study involves successfully synthesizing two triptycene-based building blocks, wherein one incorporates nitrogen and sulfur heteroatoms to enhance its efficacy in the subsequent step, that is wastewater treatment application. The evaluation covers their hydrophosphination capabilities. The subsequent chapter explores five polymer networks, combining 3D triptycene-based building blocks with heteroatom-rich 2D ones. Manipulating stoichiometry yields distinct attributes like thermal stability and controlled expansion. The 2D building block is more reactive than its triptycene-based counterparts. Moreover, triptycene-based polymers exhibit remarkable thermal stability and swelling. This research offers insights into designing polymer networks with triptycene, showing promise as efficient adsorbents for treating radioactive wastewater.
