Dynamic, Responsive Dna-Like Polymers
JOURNAL OF THE AMERICAN CHEMICAL SOCIETY(2018)
Abstract
The synthesis of thiolactone monomers that mimic natural nucleosides and engage in robust ring opening polymerizations (ROP) is herein described. As each repeat unit contains a thioester functional group, dynamic rearrangement of the polymer is feasible via thiol-thioester exchange, demonstrated here by depolymerization of the polymers and coalescing of two polymers of different molecular weight or chemical composition. This approach constitutes the first step toward a platform that enables for the routine synthesis of sequence controlled polymers via dynamic template directed synthesis.
