Metal-free 1,3-dipolar cycloaddition polymerization via prearrangement of azide and alkyne in the solid state†
Abstract
Metal-free 1,3-dipolar cycloaddition polymerization with controlled regioselectivity is achieved by pre-organizing azide and terminal alkyne functional groups in the solid state. Soluble polymers are obtained with monomers containing flexible tri- and tetra-ethylene glycol linkers.
