Synthesis of Novel Purine-based Polymers
Abstract
In this STIR project we have investigated the development of a new class of semi-rigid, highly-tailorable copolymeric materials based on purines. Synthetic efforts have been based on step-growth polymerization using Stille cross-couplings of halogenated purines and arylorganotin reagents. These studies have demonstrated the first-ever synthesis of copolymers containing purine units as the chain backbone. With the feasibility of producing these novel materials demonstrated, a wide variety of efforts have been devoted to increasing the molecular weight of the copolymer through choice of solvent, catalyst, design of the monomeric building blocks, and reaction temperature. Thermal characteristics of the synthesized poly(purines) have been examined, and the high glass transition temperatures studies suggest that the resulting polymers are semi-rigid, tough materials. Outcomes from the project provide a launching point for subsequent studies aimed at understanding how chemical information and bonding arrangements affect chain properties and translate through macroscopic properties.These materials may have utility in optoelectronic applications and may possess useful coordination, recognition, sensing, or catalytic properties.
